Description

The SLIN-06E2Ax power modules are non-isolated dc/dc conver ters that can deliver up to 6A of output current. These modules operate over a wide range of input voltage (V IN = 4.5Vdc-14Vdc) and provide a precisely regulated output voltage from 0.59Vdc to 5.5Vdc, progra mmable via an external resistor. Features include remote On/Off, adjustable output voltage, and over current and over temperatur e protection. A new feature, the Tunable Loop TM, allows the user to optimize the dynamic re sponse of the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area.

An input line fuse must be used in application. This power module can be used in a wide variety of appl ications, ranging from simple standalone operation to an integrated part of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rati ng of 6A. Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information. Note: Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature conditions.

Input Filtering The SLIN-06E2Ax module should be connected to a low ac-impedance source. A highly inductive source can affect the stability of the module. Input capacitance mu st be placed directly adjacent to the input pin of the module, to minimize input ripple voltage and ensure module stability. To minimize input voltage ripple, ceramic capacitors are recommended at the input of the module. The figure below shows the input ripple voltage for various output volt ages at 6A of load current with 1x10 µF or 1x22 µF ceramic capacitors and an input of 12V. Input Ripple Voltage (mVp-p) 100 150 200 250 300 350 400 450 1x10uF 1x22uF Output Voltage (Vdc) Note: Input ripple voltage for various output voltages with 1x10 µF or 1x22 µF ceramic capacitors at the input (6A load). Input voltage is 12V. Output Filtering The SLIN-06E2Ax modules are designed for low output ripple voltage and will meet the maximum output ripple specification with 0.1 µF ceramic and 10 µF ceramic capa citors at the output of the module. However, additional output filtering may be required by the system designer for a number of reasons. First, there may be a need to further reduce the output ripple and noise of the module. Second, the dynamic response characteristics may need to be customized to a particular load step change. To reduce the output ripple and improve the dynamic resp onse to a step load change, additional capacitance at the output can be used. Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response of the module. The figure on the next page provides output ripple information for different external capacitance values at various Vo and for a load current of 6A. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified in the electrical specification table. Optimal performance of the module can be achieved by using the Tunable Loop TM feature described later in this data sheet.

Safety Considerations For safety agency approval the power module must be inst alled in compliance with the spacing and separation requirements of the end-use safety agency standards, i.e., UL 60950-1, CSA C22.2 No. 60950-1-03, and VDE 0850:2001-12 (EN60950-1) Licensed. For the converter output to be considered meeting the requir ements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a fast-act ing fuse with a maximum rating of 6A in the positive input lead.

Signal Low (Unit Off) -0.3 - 0.8 V Signal High (Unit On) Active High 3.5 - Vin,max V The remote on/off pin open, Unit on. The SLIN-06E2Ax power modules feature an On/Off pin fo r remote On/Off operation. Two On/Off logic options are available. In the Positive Logic On/Off option, the module turns ON during a logic High on the On/Off pin and turns OFF during a logic Low. With the Negative Logi c On/Off option, the module turns OFF during logic High and ON during logic Low. The On/Off signal is always referenced to ground. For either On/Off logic option, leaving the On/Off pin disconnected will turn the module ON when input voltage is present. For positive logic modules, the circuit configuration fo r using the On/Off pin is shown in the figure below. When the external transistor Q1 is in t he OFF state, the internal PWM Enable signal is pulled high through an internal 1.5MΩ resistor and the external pullup resistor and the module is ON. When transis tor Q1 is turned ON, the On/Off pin is pulled low and the module is OFF. A suggested value for R pullup is 20kΩ. Circuit configuration for using positive On/Off logic For negative logic On/Off modules, the circuit configuration is shown below. The On/Off pin should be pulled high with an external pull-up resistor (suggested value for the 4.5V to 14V input range is 20Kohms). When transistor Q2 is in the OFF state, the On/Off pin is pulled high, transistor Q1 is turned ON and the module is OFF. To turn the module ON, Q2 is turned ON pulling the On/Off pin low, turning transistor Q1 OFF resulting in the PWM Enable pin going high. 1.5MEG VIN+ GND PWM EnableON/OFF ON/OFF MODULE I V Rpullup ON/OFF 22K 22K Circuit configuration for using negative On/Off logic 1.5MEG GND ON/OFF VIN+ + PWM Enable I VON/OFF MODULE Rpullup ON/OFF 2.05K

Over Current Protection To provide protection in a fault (out put overload) condition, the unit is e quipped with internal current-limiting circuitry and can endure current limiting continuously. At the point of current-limit inception, the unit enters hiccup mode. The unit operates normally once the output current is brought back into its specified range. Over Temperature Protection To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the over temperature threshold of 140°C is exceeded at the thermal reference point Tref. The thermal shutdown is not intended as a guarantee that the unit will survive temperatur es beyond its rating. Once the unit goes into thermal shutdown it will then wait to cool before attempting to restart. Input Under-voltage Lockout At input voltages below the input under voltage lockout limit, the module operat ion is disabled. The module will begin to operate at an input voltage above the under voltage lockout turn-on threshold. Output Voltage Programming The output voltage of the SLIN-06E2Ax modules can be pr ogrammed to any voltage from 0.59Vdc to 5.5Vdc by connecting a resistor between the Trim and GND pins of the module. Certain rest rictions apply on the output voltage set point depending on the input voltage. These ar e shown below. The Limit cu rve shows that for output voltages of 0.9V and lower, the input voltage must be lower than the maximum of 14V. The Lower Limit curve shows that for output voltages of 3.8V and higher, the input voltage needs to be larger than the minimum of 4.5V.

Table 1 VO, set (V) Rtrim (KΩ) 0.6 656.7 1.0 14.45 1.2 9.704 1.5 6.502 1.8 4.888 2.5 3.096 3.3 2.182 5.0 1.340 By using a ±0.5% tolerance trim resistor with a TC of ±100ppm, a set point tolerance of ±1.5% can be achieved as specified in the electrical specification. Remote Sense The SLIN-06E2Ax power modules have a Remote Sense featur e to minimize the effects of distribution losses by regulating the voltage at the SENSE pin. The voltage between the SENSE pin and VOUT pin must not exceed 0.5V. Note that the output voltage of the module cannot exceed the specified maximum value. This includes the voltage drop between the SENSE and Vout pins. When t he Remote Sense feature is not being used, connect the SENSE pin to the VOUT pin.

Power Good The SLIN-06E2Ax provide a Power Good (PGOOD) signal that is implemented with an open-drain output to indicate that the output voltage is within the regulati on limits of the power module. The PGOOD signal will be de- asserted to a low state if any condition such as over temp erature, over current or loss of regulation occurs that would result in the output voltage going ±10% outside the set-point value. The PGOOD terminal should be connected through a pull-up resistor (suggested value 100KΩ) to a source of 5VDC or lower. Tunable LoopT M The SLIN-06E2Ax modules have a new feature that optim izes transient response of the module called Tunable LoopTM. External capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise and to reduce output voltage deviations from the st eady-state value in the presence of dynamic load current changes. Adding external capacitance however a ffects the voltage control loop of the module, typically causing the loop to slow down with sluggish response. Larger values of external capacitance could also cause the module to become unstable. The Tunable Loop TM allows the user to externally adjust the vo ltage control loop to match the filter network connected to the output of the module. The Tunable LoopTM is implemented by connecting a series R-C between the SENSE and TRIM pins of the module, as shown in below . This R-C allows the user to externally adjust the voltage loop feedback compensation of the module. MODULE VOUT SENSE TRIM GND RTUNE CTUNE RTrim C O Circuit diagram showing connection of RTUNE and CTUNE to tune the control loop of the module Recommended values of RTUNE and CTUNE for different output capacitor combinations are given in Tables 2 and 3. Table 2 shows the recommended values of R TUNE and CTUNE for different values of ceramic output capacitors up to 470uF that might be needed for an application to m eet output ripple and noise requirements. Selecting R TUNE and CTUNE according to Table 2 will ensure stable operation of the module. In applications with tight output voltage limits in the presence of dynamic current loading, additional output capacitance will be required. Table 3 lists recommended values of R TUNE and CTUNE in order to meet 2% output voltage deviation limits for some common output voltages in t he presence of a 3A to 6A step change (50% of full load), with an input voltage of 12V.

Surface Mount Information Pick and Place The SLIN-06E2Ax modules use an open frame construction and are designed for a fully automated assembly process. The modules are fitted with a label designed to provide a large surface area for pick and place operations. The label meets all the requirements for surface mount processing, as well as safety standards, and is able to withstand reflow temperatures of up to 300oC. The label also carries product information such as part number and serial number. Nozzle Recommendations The module weight has been kept to a minimum by using open frame construction. Variables such as nozzle size, tip style, vacuum pressure and placement speed should be considered to optimize this process. The minimum recommended inside nozzle diameter for reliable operation is 3mm. The maximum nozzle outer diameter, which will safely fit within the allowable component spacing, is 7 mm. Lead Free Soldering The SLIN-06E2Ax modules are lead-free (Pb-free) and RoHS compliant and fully compatible in a Pb-free soldering process. Failure to observe the instructions below may result in the failure of or cause damage to the modules and can adversely affect long-term reliability. Pb-Free Reflow Profile Power Systems will comply with J-STD-020 Rev. C (Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices) for both Pb-free solder profiles and MSL classification procedures. This standard provides a recommended forced-air-convection reflow profile based on the volume and thickness of the package. The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown in the figure below. Soldering outside of the recommended profile requires testing to verify results and performance. MSL Rating The SLIN-06E2Ax modules have a MSL rating of 2. Storage and Handling The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of ≤ 30°C and 60% relative humidity varies according to the MSL rating (see J-STD-033A). The shelf life for dry packed SMT packages will be a minimum of 12 months from the bag seal date, when stored at the following conditions: < 40° C, < 90% relative humidity. Per J-STD-020 Rev.
