LINEAGE POWER 6 Data Sheet March 27, 2008 QBW018A0B1-TZ Series Power Modules; DC-DC converters 36-75Vdc Input; 12Vdc Output; 18A Output Current Test Configurations Design Considerations Input Source Impedance The power module should be connected to a low ac-impedance source. A highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 9, a 100μF electrolytic capacitor (ESR<0.7Ω at 100kHz), mounted close to the power module helps ensure the stability of the unit. Consult the factory for further application guidelines. Note: Measure input reflected-ripple current with a simulated source inductance (LTEST) of 12 µH. Capacitor CS offsets possible battery impedance. Measure current as shown above. Figure 9. Input Reflected Ripple Current Test Setup. Note: Use a 1.0 µF ceramic capacitor and a 10 µF aluminum or tantalum capacitor. Scope measurement should be made using a BNC socket. Position the load between 51 mm and 76 mm (2 in. and 3 in.) from the module. Figure 10. Output Ripple and Noise Test Setup. CONTACT AND DISTRIBUTION LOSSES VI(+) VO1 IO II LOAD SUPPLY VI(–) VO2 CONTACT RESISTANCE Note: All measurements are taken at the module terminals. When socketing, place Kelvin connections at module terminals to avoid measurement errors due to socket contact resistance. 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. 6095000, and VDE 0805:2001-12 (IEC60950-1). 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. The input to these units is to be provided with a maximum 15A fast-acting (or time-delay) fuse in the ungrounded lead. Figure 11. Output Voltage and Efficiency Test Setup. LINEAGE POWER 7 Data Sheet March 27, 2008 QBW018A0B1-TZ Series Power Modules; DC-DC converters 36-75Vdc Input; 12Vdc Output; 18A Output Current Feature Description Output Over Voltage clamp Overcurrent Protection The output overvoltage clamp consists of a control circuit, independent of the primary regulation loop, that monitors the voltage on the output terminals and clamps the voltage when it exceeds the overvoltage set point. The control loop of the clamp has a higher voltage set point than the primary loop. This provides a redundant voltage control that reduces the risk of output overvoltage. The module can be restarted by cycling the dc input power for at least one second or by toggling the remote on/off signal for at least one second. To provide protection in a fault output overload condition, the module is equipped with internal current-limiting circuitry and can endure current limit for few mili-seconds. If overcurrent persists beyond a few milliseconds, the module will shut down and remain latched off. The overcurrent latch is reset by either cycling the input power or by toggling the on/off pin for one second. If the output overload condition still exists when the module restarts, it will shut down again. This operation will continue indefinitely until the overcurrent condition is corrected. An auto-restart option is also available. An autorestart feature continually attempts to restore the operation until fault condition is cleared. Remote On/Off Two remote on/off options are available. Positive logic remote on/off 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 turns the module off during a logic high and on during a logic low. Negative logic, device code suffix "1," is the factory-preferred configuration. The on/off circuit is powered from an internal bias supply. To turn the power module on and off, the user must supply a switch to control the voltage between the on/off terminal and the Vi (-) terminal (Von/off). The switch can be an open collector or equivalent (see Figure 12). A logic low is Von/off = 0.0V to 0.8V. The typical Ion/off during a logic low is 10 µA. The switch should maintain a logiclow voltage while sinking 10µA. During a logic high, the maximum Von/off generated by the power module is 5.0V. The maximum allowable leakage current of the switch at Von/off = 2.0V is 6.0µA. If using an external voltage source, the maximum voltage V on/off on the pin is 14.0V with respect to the Vi (-) terminal. If not using the remote on/off feature, perform one of the following to turn the unit on: For negative logic, short ON/OFF pin to VI(-). For positive logic: leave ON/OFF pin open. Ion/off + Over Temperature Protection These modules feature an overtemperature protection circuit to safeguard against thermal damage. The circuit shuts down and latches off the module when the maximum device reference temperature is exceeded. The module can be restarted by cycling the dc input power for at least one second or by toggling the remote on/off signal for at least one second. Input Under/Over Voltage Lockout At input voltages above or below the input under/over voltage lockout limits, module operation is disabled. The module will begin to operate when the input voltage level changes to within the under and overvoltage lockout limits. ON/OFF Von/off – VO(+) LOAD VI(+) VO(–) VI(–) Figure 12. Remote On/Off Implementation. LINEAGE POWER 8 QBW018A0B1-TZ Series Power Modules; DC-DC converters 36-75Vdc Input; 12Vdc Output; 18A Output Current 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. Heat-dissipating components are mounted on the top side of the module. Heat is removed by conduction, convection and radiation to the surrounding environment. Proper cooling can be verified by measuring the thermal reference temperatures (TH1 and TH2). Peak temperatures (TH) occurs at the positions indicated in Figure 13. For reliable operation these temperatures should not exceed the listed temperature threshold. TH2 TH1 33.9 (1.33) 23.6 (.93) (14-16) show the maximum output current that can be delivered by each module in the respective orientation without exceeding the maximum TH temperatures versus local ambient temperature (TA) for air flows of 1 m/s (200 ft./min.), 2m/s (400 ft./min.) and 3m/s (600 ft./min.). The use of Figures 14 - 15 are shown in the following example: OUTPUT CURRENT, IO (A) Data Sheet March 27, 2008 20 15 10 3m/s (600LFM) 2m/s (400LFM) 5 1m/s (200LFM) 0 0 20 40 60 80 100 LOCAL AMBIENT TEMPERATURE, TA (°C) Figure 14.

The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to Lineage Power Board Mounted Power Modules: Soldering and Cleaning Application Note. Through-Hole Lead-Free Soldering Information 2m/s (400LFM) 0 For additional layout guide-lines, refer to the PIM200X and FLT007A0 Input Filter Module data sheets. The RoHS-compliant 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 Pb-free wave soldering processes. A maximum preheat rate of 3°C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210°C. For Pb solder, the recommended pot temperature is 260°C, while the Pb-free solder pot is 270°C max. Not all RoHS-compliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process.
