[Type text] [Type text] [Type text] September 16 - 2017 A.04 HBR Series of Railway Half -Brick Up to 100 Watts DC-DC Converter Operating Temperature Range The HBR series of converters is rated to operate over a wide case temperature range of - 40°C to +100°C. Consideration must be given to the de-rating curves when ascertaining maximum power that can be drawn from the converter. The maximum power drawn from half brick models is influenced by usual factors, such as:
- Input voltage range
- Output load current
- Forced air or natural convection Output Voltage Adjustment The output voltage for the on HBR series outputs of 3.3, 5 and 24 Volts models is adjustable within the range of +10% to – 10%. For the 12, 15, 24 and 48 Volts model, see input and output trim curves. Over Current Protection The converter is protected against over current or short circuit conditions. At the instance of current -limit inception, the module enters a hiccup mode of operation, whereby it shuts down and automatically attempts to restart. While the fault condition exists, the module will remain in this hiccup mode, and can remain in this mode until the fault is cleared. The unit operates normally once the output current is reduced back into its specified range. Output over Voltage Protection The output overvoltage protection consists of an internal circuit that limits the output voltage. If more accurate output over voltage protection is required , then an external circuit can be used via the remote on/off pin. Remote On/Off The On/Off input pin permits the user to turn the power module on or off via a system signal. Two remote on/off options are available. Positive logic turns the module on during a logic high voltage on the On/Off pin, and off during a logic low. The O n/Off pin is internally pulled up through a resistor. A properly de -bounced mechanical switch, open c ollector transistor, or FET can be used to drive the input of the On/Off pin. If not using the remote on/off feature, leave the On/Off pin open. UVLO (Under Voltage Lock Out) Input under voltage lockout is standard with this converter. At input voltages below the input under voltage lockout limit, the module operation is disabled. Over Temperature Protection These modules have an over temperature protection circuit to safeguard against thermal damage. When the case temperature rises above over temperature shutdown threshold, the converter will shut down to protect it from overheating. The module will automatically restart after it cools down. Recommended Layout, PCB Footprint and Soldering Information The user must ensure that other components and metal in the vicinity of the converter meet the spacing requirements to which the system is approved. Low resistance and low inductance PCB layout should be used where possible. Proper attention must also be given to low impedance tracks between power module, input and output grounds. The recommended footprints and soldering profiles are shown in the next two figures. Note： 1. Soldering Materials: Sn/Cu/Ni 2. Ramp up rate during preheat: 1.4 ℃ /Sec (From 50 ℃ to 100℃) 3. Soaking temperature: 0.5 ℃ /Sec (From 100 ℃ to 130℃), 60±20 seconds 4. Peak temperature: 260 ℃, above 250℃ 3~6 Seconds 5. Ramp rate during cooling: - 10.0 ℃/Sec (From 260 ℃ to 150℃) Convection Requirements for Cooling To predict the approximate cooling needed for the half brick module, refer to the power de- rating curves in the next section These de-rating curves are approximations of the ambient temperatur es and airflows required to keep the power module temperature below its maximum rating. Once the module is assembled in the actual system, the module’s temperature should be monitored to ensure it does not exceed 100°C as being measured at the center of th e top of the case (thus verifying proper cooling). Thermal Considerations The power module operates in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat is removed by condu ction, convection, and radiation to the surrounding environment. The test data is presented in the next section . The power output of the module should not be allowed to exceed rated power (Vo_set x Io_max).

[Type text] [Type text] [Type text] September 16 - 2017 A.04 HBR Series of Railway Half -Brick Up to 100 Watts DC-DC Converter Test Set-Up The basic test set -up to measure efficiency , load regulation , line regulation and other parameters is shown in the next figure . When testing the converter under any transient conditions , the user should ensure that the transient response of the source is sufficient to p ower the equipment under test. Below is the calculation of: 1- Efficiency 2- Load regulation 3- Line regulation The value of efficiency is defined as: %100×× ×= IinVin IoVoη Where: Vo is output voltage, Io is output current, Vin is input voltage, Iin is input current. The value of load regulation is defined as: %100. ×−= NL NLFL V VVregLoad Where: VFL is the output voltage at full load VNL is the output voltage at no load The value of line regulation is defined as: Where: VHL is the output voltage of maximum input voltage at full load. V LL is the output voltage of minimum input voltage at full load. HBR Series Test Setup Output Voltage Adjustment Output may be externally trimmed (±10%) with a fixed resistor or an external trim -pot as shown (optional). Model specific formulas for calculating trim resistors are available upon request as a separate document Output voltage trim circuit configuration In order to trim the voltage up or down, one needs to connect the trim resistor either between the trim pin and -Vo for trim -up or between trim pin and +Vo for trim-down. The output voltage trim range is ±10%. This is shown in the figure below Output voltage trim up circuit %100. ×−= LL LLHL V VVregLine Page 10 of 16
[Type text] [Type text] [Type text] September 16 - 2017 A.04 HBR Series of Railway Half -Brick Up to 100 Watts DC-DC Converter Output voltage trim down circuit The recommend Resistor Values: For HBR series, R trim_up is defined as: Where: 1- R trim_up is the external resistor in KΩ. 2- V o_nom is the nominal output voltage. 3- Vo is the desired output voltage. 4- R1, R2, R3 and V r are internal components. For example: to trim -up the output voltage of the HBR113S12 -8.3 module by 5% to 12.6V, R trim_up is calculated as follows: Vo – V o_nom = 12.6 – 12 = 0.6V R1 = 9.1 K Ω, R2 = 51 KΩ, R3 = 5.1K Ω, Vr= 2.5 V , Vf=0.46 V On the other hand, R trim_down is defined as: Where: 1- R trim_down is the external resistor in K Ω. 2- V o_nom is the nominal output voltage 3- Vo is the desired output voltage. 4- R1, R2, R3 and V r are internal components. For example: to trim -down the output voltage of the HBR113S12- 8.3 module by 5% to 11.4V, R trim_down is calculated as follows: Vo_nom – V o = 12 – 11.4 = 0.6 V R1 = 9.1 KΩ, R2 = 51 KΩ, V r = 2.5 V Vout (V) R1 (KΩ) R2 (KΩ) R3 (KΩ) VR (KΩ) Vf (KΩ) 12 9.1 51 5.1 2.5 0.46 15 9.1 51 5.1 2.5 0.46 24 20 130 6.2 2.5 0.46 48 40.2 270 5.1 2.5 0.46 Page 11 of 16
[Type text] [Type text] [Type text] September 16 - 2017 A.04 HBR Series of Railway Half -Brick Up to 100 Watts DC-DC Converter Output Remote Sensing The HBR SERIES converter has the capability to remotely sense both lines of its output. This feature moves the effective output voltage regulation point from the output of the unit to the point of connection of the remote sense pins. This feature automatically ad justs the real output voltage of the HBR series in order to compensate for voltage drops in distribution and maintain a regulated voltage at the point of load. The remote -sense voltage range is: [(+Vout) - (-Vout)] – [(+Sense) – (-Sense)] ≦ 10% of Vo_nominal If the remote sense feature is not to be used, the sense pins should be connected locally. The +Sense pin should be connected to the +Vout pin at the module and the - Sense pin should be connected to the -Vout pin at the module. This is shown in t he schematic below. Note: Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the out put voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim . The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim, the output voltage of the module can be increased and consequently increase the power output of the module if output current remains unchanged. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power (Maximum rated power = V o,set x Io,max) Output Ripple and Noise Output ripple and noise is measured with 1.0uF ceramic and 10uF solid tantalum capacitors across the output. Output Capacitance For good transient response, low ESR output capacitors should be located close to the point of load. PCB design emphasizes low resistance and inductance tracks in consideration of high current applications. Output capacitors with their associated ESR values have an impact on loop stability and bandwidth. For absolute maximum value of HBR series’ output capacitance, please refer to page 3 Maximum Output Capacitance. For values larger than this, please contact your local DATEL ’s representative. +Vin -Vin -Vo +Vo Resistor Load 1uF Vin BNC To Scope +Sense -Sense Trim 10uF Page 12 of 16
