Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 7, a 33F electrolytic capacitor (ESR<0.7 at 100kHz), mounted close to the power module helps ensure the stability of the unit.

IO Efficiency = VIN. IIN x 100 % Safety Considerations For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL 60950-1-3, CSA C22.2 No. 60950-00, and VDE 0805 (IEC60950, 3rd Edition). If the input source is non-SELV (ELV or a hazardous voltage greater than 60 Vdc and less than or equal to 75Vdc), for the module's output to be considered as meeting the requirements for safety extra-low voltage (SELV), all of the following must be true: The input source is to be provided with reinforced insulation from any other hazardous voltages, including the ac mains. One VIN pin and one VOUT pin are to be grounded, or both the input and output pins are to be kept floating. The input pins of the module are not operator accessible. Another SELV reliability test is conducted on the whole system (combination of supply source and subject module), as required by the safety agencies, to verify that under a single fault, hazardous voltages do not appear at the module's output. Note: Do not ground either of the input pins of the module without grounding one of the output pins. This may allow a non-SELV voltage to appear between the output pins and ground. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. For input voltages exceeding -60 Vdc but less than or equal to -75 Vdc, these converters have been evaluated to the applicable requirements of BASIC INSULATION between secondary DC MAINS DISTRIBUTION input (classified as TNV-2 in Europe) and unearthed SELV outputs. The input to these units is to be provided with a maximum 3A time-delay fuse in the ungrounded lead. Feature Description Remote On/Off 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. Negative logic remote on/off, device code suffix "1", turns the module off during a logic high and on during a logic low. May 4, 2015 (c)2012 General Electric Company. All rights reserved. Page 6 GE Data Sheet SHHD001A3B Hammerhead Series; DC-DC Converter Power Modules 18-75Vdc Input; 12Vdc, 1.3A, 15W Output Vin+ Vout+ Trimming allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting an external resistor between the TRIM pin and either the Vout+ pin or the Vout- pin. Trim Down - Decrease Output Voltage Ion/off ON/OFF TRIM Von/off Vin- By connecting an external resistor between the TRIM pin and Vout+ pin (Radj-down), the output voltage set point decreases (see figure 11). The following equation determines the external resistor value to obtain an output voltage change from Vo,nom to the desired Vo,adj: Vout- (Vo, adj 2.5) 10000 Radj down 5100 (Vo, nom Vo, adj) Figure 10. Circuit configuration for using Remote On/Off Implementation. To turn the power module on and off, the user must supply a switch (open collector or equivalent) to control the voltage (Von/off) between the ON/OFF terminal and the VIN(-) terminal. Logic low is 0V Von/off 0.8V. The maximum Ion/off during a logic low is 1mA, the switch should be maintain a logic low level whilst sinking this current. During a logic high, the typical Von/off generated by the module is 2.4V, and the maximum allowable leakage current at Von/off = 2.4V is 25A. Vin+ Vout+ Radj-down ON/OFF RLOAD TRIM Vin- Vout- If not using the remote on/off feature: For positive logic, leave the ON/OFF pin open. Figure 11. Circuit Configuration to Decrease Output Voltage. For negative logic, short the ON/OFF pin to VIN(-). Trim Up - Increase Output Voltage Overcurrent Protection By connecting an external resistor between the TRIM pin and Vout- pin (Radj-up), the output voltage set point increases (see figure 12). The following equation determines the external resistor value to obtain an output voltage change from Vo,nom to the desired Vo,adj: To provide protection in a fault (output overload) condition, the unit is equipped 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. The average output current during hiccup is 10% IO, max. Overtemperature Protection To provide protection under certain fault conditions, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the thermal reference point Tref (Figure 17, exceeds 125oC (typical), but the thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. The module will automatically restart upon cool-down to a safe temperature. 25,000 5110 Radj up (Vo, adj 12) Vin+ Vout+ ON/OFF RLOAD TRIM Radj-up Input Undervoltage Lockout At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will only begin to operate once the input voltage is raised above the undervoltage lockout turn-on threshold, VUV/ON. Once operating, the module will continue to operate until the input voltage is taken below the undervoltage turn-off threshold, VUV/OFF. Over Voltage Protection The output overvoltage protection shall consist of circuitry that independently monitors the output voltage, and shuts the module down if the output voltage exceeds specified limits. The module shall contain hiccup restart capability. Output Voltage Programming May 4, 2015 Vin- Vout- Figure 12. Circuit Configuration to Increase Output Voltage. Feature Descriptions (continued) The combination of the output voltage adjustment and the output voltage initial tolerance must not exceed the allowable trim range of 90% to 110% of the nominal output voltage as measured between the Vout+ and Vout- pins. The SHHD power modules have a fixed current-limit set point. Therefore, as the output voltage is adjusted down, the available output power is reduced. (c)2012 General Electric Company.

To trim module down to 11.5V: (11.5 2.5) 10000 Radj down 5110 (12.0 11.5) Radj down 174,890 Load Share -P Versions Modules with "P" in the product code are configured with active droop load sharing capability. Best load current sharing balance is achieved when the output traces from each module have the same external Vout+ and Vout- resistance (length x width) to the location where the traces merge. The module incorporates diode rectification which insures no reverse current during parallel startup if one module is ahead of others during turn-on. Up to 4 modules may be paralleled for increased load power. Maintain same temperature for all modules to insure best load share balance. Thermal Considerations The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability.The thermal data presented here is based on physical measurements taken in a wind tunnel, using automated thermo-couple instrumentation to monitor key component temperatures: FETs, diodes, control ICs, magnetic cores, ceramic capacitors, opto-isolators, and module pwb conductors, while controlling the ambient airflow rate and temperature. For a given airflow and ambient temperature, the module output power is increased, until one (or more) of the components reaches its maximum derated operating temperature, as defined in IPC-9592A. This procedure is then repeated for a different airflow or ambient temperature until a family of module output derating curves is obtained. Figure 13 Output Current Active Droop, -P Option.

Page 9 GE Data Sheet SHHD001A3B Hammerhead Series; DC-DC Converter Power Modules 18-75Vdc Input; 12Vdc, 1.3A, 15W Output Layout Considerations Nozzle Recommendations The SHHD power module series are low profile in order to be used in fine pitch system card architectures. As such, component clearance between the bottom of the power module and the mounting board is limited. Avoid placing copper areas on the outer layer directly underneath the power module. Also avoid placing via interconnects underneath the power module. The module weight has been kept to a minimum by using open frame construction. Even so, they have a relatively large mass when compared with conventional SMT components. Variables such as nozzle size, tip style, vacuum pressure and placement speed should be considered to optimize this process. For additional layout guide-lines, refer to the FLTR100V10 data sheet. The SHHD family of power modules is available for either Through-Hole (TH) or Surface Mount (SMT) soldering. Through-Hole Soldering Information The RoHS-compliant (Z codes) through-hole products use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant components. They are designed to be processed through single or dual wave soldering machines. The pins have an RoHS-compliant finish that is compatible with both Pb and Pbfree wave soldering processes. A maximum preheat rate of 3C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210C. For Pb solder, the recommended pot temperature is 260C, while the Pb-free solder pot is 270C max. The Through Hole module is also compatible with paste-in-hole reflow soldering. Refer to the Reflow Soldering Information section for process details. If additional information is needed, please consult with your GE representative for more details. Surface Mount Information Pick and Place The SHHD-SR series of DC-to-DC power converters use an open-frame construction and are designed for surface mount assembly within a fully automated manufacturing process. The SHHD-SR series modules are designed to use the main magnetic component surface to allow for pick and place. The minimum recommended nozzle diameter for reliable operation is 5mm. The maximum nozzle outer diameter, which will safely fit within the allowable component spacing, is 6.5mm. Oblong or oval nozzles up to 11 x 6 mm may also be used within the space available. For further information please contact your local GE Technical Sales Representative. Reflow Soldering Information These power modules are large mass, low thermal resistance devices and typically heat up slower than other SMT components. It is recommended that the customer review data sheets in order to customize the solder reflow profile for each application board assembly. The following instructions must be observed when SMT soldering these units. Failure to observe these instructions may result in the failure of or cause damage to the modules, and can adversely affect long-term reliability. There are several types of SMT reflow technologies currently used in the industry. These surface mount power modules can be reliably soldered using natural forced convection, IR (radiant infrared), or a combination of convection/IR. The recommended linear reflow profile using Sn/Pb solder is shown in Figure 21 and 22. For reliable soldering the solder reflow profile should be established by accurately measuring the modules CP connector temperatures. 300 P eak Temp 235oC REFLOW TEMP (C) 250 200 Heat zo ne max 4oCs -1 Co o ling zo ne 1-4oCs -1 150 100 50 So ak zo ne 30-240s Tlim above 205oC P reheat zo ne max 4oCs -1 0 REFLOW TIME (S) Figure 21.
