General Information Reliability The failure rate (λ) and mean time between failures (MTBF= 1/λ) is calculated at max output power and an operating ambient temperature (TA) of +40°C. Flex Power Modules uses Telcordia SR-332 Issue 2 Method 1 to calculate the mean steady-state failure rate and standard deviation (σ). Telcordia SR-332 Issue 2 also provides techniques to estimate the upper confidence levels of failure rates based on the mean and standard deviation. Mean steady-state failure rate, λ Std. deviation, σ 112 nFailures/h 8.7 nFailures/h MTBF (mean value) for the PKB 4313D series = 8.9 Mh. MTBF at 90% confidence level = 8.1 Mh Compatibility with RoHS requirements The products are compatible with the relevant clauses and requirements of the RoHS directive 2011/65/EU and have a maximum concentration value of 0.1% by weight in homogeneous materials for lead, mercury, hexavalent chromium, PBB and PBDE and of 0.01% by weight in homogeneous materials for cadmium.

IEC/EN/UL 60950-1 contains requirements to prevent injury or damage due to the following hazards:

• Electrical shock
• Energy hazards
• Fire
• Mechanical and heat hazards
• Radiation hazards
• Chemical hazards On-board DC/DC converters and DC/DC regulators are defined as component power supplies. As components they cannot fully comply with the provisions of any safety requirements without “conditions of acceptability”. Clearance between conductors and between conductive parts of the component power supply and conductors on the board in the final product must meet the applicable safety requirements. Certain conditions of acceptability apply for component power supplies with limited stand-off (see Mechanical Information and Safety Certificate for further information). It is the responsibility of the installer to ensure that the final product housing these components complies with the requirements of all applicable safety standards and regulations for the final product. Component power supplies for general use should comply with the requirements in IEC/EN/UL 60950-1 Safety of Information Technology Equipment. Product related standards, e.g. IEEE 802.3af Power over Ethernet, and ETS-300132-2 Power interface at the input to telecom equipment, operated by direct current (dc) are based on IEC/EN/UL 60950-1 with regards to safety. Flex Power Modules DC/DC converters, Power interface modules and DC/DC regulators are UL 60950-1 recognized and certified in accordance with EN 60950-1. The flammability rating for all construction parts of the products meet requirements for V-0 class material according to IEC 60695-11-10, Fire hazard testing, test flames – 50 W horizontal and vertical flame test methods. Isolated DC/DC converters The product may provide basic or functional insulation between input and output according to IEC/EN/UL 60950-1 (see Safety Certificate), different conditions shall be met if the output of a basic or a functional insulated product shall be considered as safety extra low voltage (SELV). For basic insulated products (see Safety Certificate) the output is considered as safety extra low voltage (SELV) if one of the following conditions is met:
• The input source provides supplementary or double or reinforced insulation from the AC mains according to IEC/EN/UL 60950-1.
• The input source provides functional or basic insulation from the AC mains and the product’s output is reliably connected to protective earth according to IEC/EN/UL 60950-1. For functional insulated products (see Safety Certificate) the output is considered as safety extra low voltage (SELV) if one of the following conditions is met:
• The input source provides double or reinforced insulation from the AC mains according to IEC/EN/UL 60950-1.
• The input source provides basic or supplementary insulation from the AC mains and the product’s output is reliably connected to protective earth according to IEC/EN/UL 60950-1.
• The input source is reliably connected to protective earth and provides basic or supplementary insulation according to IEC/EN/UL 60950-1 and the maximum input source voltage is 60 Vdc. Galvanic isolation between input and output is verified in an electric strength test and the isolation voltage (Viso) meets the voltage strength requirement for basic insulation according to IEC/EN/UL 60950-1. It is recommended to use a slow blow fuse at the input of each DC/DC converter. If an input filter is used in the circuit the fuse should be placed in front of the input filter. In the rare event of a component problem that imposes a short circuit on the input source, this fuse will provide the following functions:
• Isolate the fault from the input power source so as not to affect the operation of other parts of the system
• Protect the distribution wiring from excessive current and power loss thus preventing hazardous overheating PKB4000D series Fully regulated DC-DC Converters Input 36-75 V, Output up to 25 A / 300 W 28701-BMR674 01 Rev G July 2019 © Flex Technical Specification

It is also important to consider the stand-off of the product. If a ground layer is used, it should be connected to the output of the product and to the equipment ground or chassis. A ground layer will increase the stray capacitance in the PWB and improve the high frequency EMC performance. Output ripple and noise Output ripple and noise is measured according to figure below.

The input voltage range 36 to 75 Vdc meets the requirements of the European Telecom Standard ETS 300 132-2 for normal input voltage range in –48 and -60 Vdc systems, -40.5 to -57 V and -50 to -72 V respectively. At input voltages exceeding 75 V, the power loss will be higher than at normal input voltage and TP1 must be limited to absolute max +125°C. The absolute maximum continuous input voltage is 80 Vdc. Above 42 V the product operates with normal regulation with constant output voltage and constant maximum power. Below

42 V the output voltage starts to track the input voltage with a

fixed proportion, keeping a duty-cycle guard band for regulation. The product operates down below 36 V before the internal under voltage lock out turns off the product. Short duration transient disturbances can occur on the DC distribution and input of the product when a short circuit fault occurs on the equipment side of a protective device (fuse or circuit breaker). The voltage level, duration and energy of the disturbance are dependent on the particular DC distribution network characteristics and can be sufficient to damage the product unless measures are taken to suppress or absorb this energy. The transient voltage can be limited by capacitors and other energy absorbing devices like Zener diodes connected across the positive and negative input conductors at a number of strategic points in the distribution network. The end-user must secure that the transient voltage will not exceed the value stated in the Absolute maximum ratings. ETSI TR 100 283 examines the parameters of DC distribution networks and provides guidelines for controlling the transient and reduce its harmful effect. Turn-off Input Voltage The products monitor the input voltage and will turn on and turn off at predetermined levels. The minimum hysteresis between turn on and turn off input voltage is 2.5 V. Remote Control (RC) The products are fitted with a remote control function referenced to the primary negative input connection (-In), with negative and positive logic options available. The RC function allows the product to be turned on/off by an external device like a semiconductor or mechanical switch. The RC pin has an internal pull up resistor of 10 kΩ to +5V. The external device must provide a minimum required sink current to guarantee a voltage not higher than maximum voltage on the RC pin (see Electrical characteristics table). When the RC pin is left open, the voltage generated on the RC pin is 5 V. The standard product is provided with “negative logic” RC. To turn off the product the RC pin should be left open, or connected to a voltage higher than 4 V referenced to -In. In situations where it is desired to have the product to power up automatically without the need for control signals or a switch, the RC pin can be wired directly to –In. To turn on the product the RC pin should be lower than 1V referenced to –In. The second option is “positive logic” remote control, which can be ordered by adding the suffix “P” to the end of the part number. When the RC pin is left open, the product starts up automatically when the input voltage is applied. Turn off is achieved by connecting the RC pin to the –In, or a voltage lower than 1V referenced to -In. The product will restart automatically when this connection is opened. The RC function incorporates a short delay in order to not trigger on glitches. Typically this filter has a settling time of 0.1-0.5 ms. This setup reduces the risk that the noise may cause the converter to shut down or power up accidently. See Design Note 021 for detailed information. Input and Output Impedance The impedance of both the input source and the load will interact with the impedance of the product. It is important that the input source has low characteristic impedance. The products are designed for stable operation with a minimum of 100 uF external capacitors connected to the input. The electrolytic capacitors will be degraded in low temperature and the ESR value may increase. The needed input capacitance in low temperature should be equivalent to 100 uF at 20° C. This means that the input capacitor value may need to be substantially larger to guarantee a stable input at low temperatures. The performance in some applications can be enhanced by addition of external capacitance as described under External Decoupling Capacitors. The minimum required capacitance value depends on the output power and the input voltage. The higher output power the higher input capacitance is needed. External Decoupling Capacitors When powering loads with significant dynamic current requirements, the voltage regulation at the load can be improved by addition of decoupling capacitors at the load. The most effective technique is to locate low ESR ceramic and electrolytic capacitors as close to the load as possible, using several parallel capacitors to lower the effective ESR. The ceramic capacitors will handle high-frequency dynamic load changes while the electrolytic capacitors are used to handle low frequency dynamic load changes. It is equally important to use low resistance and low inductance PWB layouts and cabling.

External decoupling capacitors will become part of the product’s control loop. The control loop is optimized for a wide range of external capacitance and the maximum and minimum recommended value that could be used without any additional analysis is found in the Electrical specification. The ESR of the capacitors is a very important parameter. Stable operation is guaranteed with a verified ESR value of >1 mΩ across the output connections. For further information please contact your local Ericsson Power Modules representative. Hybrid Regulated Ratio (HRR) The product uses two regulation modes. The regulated ratio mode let the regulator track the Vin with a fixed proportion, still with a guard band for load and transient regulation. The hybrid regulated mode swaps seamlessly from a ratio regulated mode to a normally regulated mode above a certain input voltage. See Output Characteristics in the Electrical Specification. HRR uses a fast adaption system and a slow adaption system to react to both fast and slow input voltage changes to provide an input voltage feed-forward function. The fast adaption system prevents the converter to change output voltage very rapid. It filters sudden input voltage changes. The slow adaption system does not let fast input voltage transients through in the regulated ratio mode, it just slowly adapts to the new input voltage. When the input voltage changes the tracking system needs up to 3 ms to fully respond. In the normally regulated mode the tracking will be saturated and the converter regulates towards a precision reference voltage instead making it almost unsusceptible to transients. Controlled low external output capacitor charge current at input voltage step Due to the slow adaption system the HRR product efficiently reduces those charge currents for the external capacitors during an input voltage transient or level shift. HRR product output at input voltage step 36-75 V, 1 ms/div Bottom trace – input voltage change 36-75 V, 20 V/div Top trace – resulting output voltage change, 1 V/div Input voltage transient suppression The hybrid regulated product effectively suppresses input voltage transients. This applies to both short duration transients and step-like level shifts of the input voltage. The amplitude of the output transients resulting of short duration transient at the input voltage will be less than 1V. In case of a step-like level shift of the input voltage, the output voltage will rise to a new regulated ratio output voltage or to 12V depending of the final value of the input voltage step. The hybrid regulated ratio prevents overshoots and undershoots in association with this transition. These capabilities significantly reduce the requirements on input transient response of Point of Load regulators fed from this product. Parallel Operation This product is not designed for paralleling without using external current sharing circuits. See Design Note 006 for detailed information. Over Temperature Protection (OTP) The products are protected from thermal overload by an internal over temperature shutdown circuit. When TP1 as defined in thermal consideration section exceeds 130°C the product will shut down. The product will make continuous attempts to start up (non-latching mode) and resume normal operation automatically when the temperature has dropped >10°C below the temperature threshold. Over Voltage Protection (OVP) The products have output over voltage protection that will shut down the product in over voltage conditions. The product will resume normal operation automatically after removal of the over voltage condition. The OVP setpoint can be found in the Electrical Specification. Over Current Protection (OCP) The products include current limiting circuitry for protection at continuous overload. The OCP works in a hiccup mode and will make continous attempts to start up and will resume normal operation automatically after removal of the over current condition. The load distribution should be designed for the specified maximum output short circuit current. Pre-bias Start-up The product has a Pre-bias start up functionality and will not sink current during start up if a pre-bias load is present at the output terminals.

The products are designed to operate in different thermal environments and sufficient cooling must be provided to ensure reliable operation. For products mounted on a PWB without a baseplate attached, cooling is achieved mainly by conduction, from the pins to the host board, and convection, which is dependant on the airflow across the product. Increased airflow enhances the cooling of the product. The Output Current Derating graph found in the Output section for each model provides the available output current vs. ambient air temperature and air velocity at VI = 53 V. The product is tested on a 254 x 254 mm, 35 µm (1 oz), 16-layer test board mounted vertically in a wind tunnel with a cross-section of 608 x 203 mm. For products with baseplate used in a sealed box/cold wall application, cooling is achieved mainly by conduction through the cold wall. The Output Current Derating graphs are found in the Output section for each model. The product performance has been tested in a sealed box presented in the figure below. The ambient temperature (inside the box) has been set to 85°C. The cold wall temperature varied. See Design Note 028 for further details. Definition of product operating temperature The temperature at the positions (TP1, TP2) should not exceed the maximum temperatures in the table below. The number of measurement points may vary with different thermal design and topology. Temperatures above maximum measured at the reference point P1, P2 are not allowed and may cause permanent damage.

Ambient Temperature Calculation For products with base plate the maximum allowed ambient temperature can be calculated by using the thermal resistance. 1. The power loss is calculated by using the formula ((1/η) - 1) × output power = power losses (Pd). 2. Find the thermal resistance (Rth) in the Thermal Resistance graph found in the Output section for each model. Note that the thermal resistance can be significantly reduced if a heat sink is mounted on the top of the base plate. Calculate the temperature increase (∆T). ∆T = Rth x Pd 3. Max allowed ambient temperature is: Max TP1 - ∆T. E.g. PKB4313D at 1m/s: 3. 125 °C – 59°C = max ambient temperature is 66°C The actual temperature will be dependent on several factors such as the PWB size, number of layers and direction of airflow.

Soldering Information - Surface Mounting The surface mount product is intended for forced convection or vapor phase reflow soldering in SnPb and Pb-free processes. The reflow profile should be optimised to avoid excessive heating of the product. It is recommended to have a sufficiently extended preheat time to ensure an even temperature across the host PWB and it is also recommended to minimize the time in reflow. A no-clean flux is recommended to avoid entrapment of cleaning fluids in cavities inside the product or between the product and the host board, since cleaning residues may affect long time reliability and isolation voltage. General reflow process specifications SnPb eutectic Pb-free Average ramp-up (TPRODUCT) 3°C/s max 3°C/s max Typical solder melting (liquidus) temperature TL 183°C 221°C Minimum reflow time above TL 60 s 60 s Minimum pin temperature TPIN 210°C 235°C Peak product temperature TPRODUCT 225°C 260°C Average ramp-down (TPRODUCT) 6°C/s max 6°C/s max Maximum time 25°C to peak 6 minutes 8 minutes TPRODUCT maximum TPIN minimum Time Pin profile Product profile TL Time in reflow Time in preheat / soak zone Time 25°C to peak Temperature Minimum Pin Temperature Recommendations Pin number 4 is chosen as reference location for the minimum pin temperature recommendation since this will likely be the coolest solder joint during the reflow process. SnPb solder processes For SnPb solder processes, a pin temperature (TPIN) in excess of the solder melting temperature, (TL, 183°C for Sn63Pb37) for more than 60 seconds and a peak temperature of 220°C is recommended to ensure a reliable solder joint. For dry packed products only: depending on the type of solder paste and flux system used on the host board, up to a recommended maximum temperature of 245°C could be used, if the products are kept in a controlled environment (dry pack handling and storage) prior to assembly. Lead-free (Pb-free) solder processes For Pb-free solder processes, a pin temperature (TPIN) in excess of the solder melting temperature (TL, 217 to 221°C for SnAgCu solder alloys) for more than 60 seconds and a peak temperature of 245°C on all solder joints is recommended to ensure a reliable solder joint. Maximum Product Temperature Requirements Top of the product PWB near pin 2 is chosen as reference location for the maximum (peak) allowed product temperature (TPRODUCT) since this will likely be the warmest part of the product during the reflow process. SnPb solder processes For SnPb solder processes, the product is qualified for MSL 1 according to IPC/JEDEC standard J-STD-020C. During reflow TPRODUCT must not exceed 225 °C at any time. Pb-free solder processes For Pb-free solder processes, the product is qualified for MSL 3 according to IPC/JEDEC standard J-STD-020C. During reflow TPRODUCT must not exceed 260 °C at any time. Dry Pack Information Products intended for Pb-free reflow soldering processes are delivered in standard moisture barrier bags according to IPC/JEDEC standard J-STD-033 (Handling, packing, shipping and use of moisture/reflow sensitivity surface mount devices). Using products in high temperature Pb-free soldering processes requires dry pack storage and handling. In case the products have been stored in an uncontrolled environment and no longer can be considered dry, the modules must be baked according to J-STD-033.
