The QBK033A0B series operate off an input voltage range from 36 to 60Vdc and provide up to 33A output current at 12V in an industry standard quarter brick. The converter incorporates synchronous rectification technology and innovative packaging techniques to achieve efficiency reaching 94.5% at 12V full load. This leads to lower power dissipations such that for many applications a heat sink is not required. The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Builtin filtering for both input and output minimizes the need for external filtering.

An input line fuse must always be used. This power module can be used in a wide variety of applications, 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 rating of 30 A (see Safety Considerations section). 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.

A highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 9, a 100F electrolytic capacitor (ESR<0.7 at 100kHz), mounted close to the power module helps ensure the stability of the unit. Consult the factory for further application guidelines. Safety Considerations Note: Measure input reflected-ripple current with a simulated source inductance (LTEST) of 12 H. Capacitor CS offsets possible battery impedance. Measure current as shown above. Figure 9. Input Reflected Ripple Current Test Setup. Note: Use a 1.0 F ceramic capacitor and a 10 F aluminum or 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 1950, CSA C22.2 No. 60950-00, and VDE rd 0805:2001-12 (IEC60950 3 Ed). 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. 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: 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 30 A fast-acting (or time-delay) fuse in the unearthed lead. 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. Figure 11. Output Voltage and Efficiency Test Setup. LINEAGE POWER 7 Data Sheet January 26, 2011 QBK033A0B Series Power Modules; dc-dc Converters 36 - 60 Vdc Input; 12Vdc Output; 33A Output Current Feature Descriptions Output Overvoltage 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. To provide protection in a fault output overload condition, the module is equipped with internal current-limiting circuitry and can endure current limiting for a few miliseconds. If the overcurrent condition 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 auto-restart feature continually attempts to restore the operation until fault condition is cleared. Overtemperature 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. 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 = -0.3V to 0.8V. The typical Ion/off during a logic low is 10 A. The switch should maintain a logic-low voltage while sinking 10A. During a logic high, the maximum Von/off generated by the power module is 3.5V. The maximum allowable leakage current of the switch at Von/off = 2.0V is 4A. If using an external voltage source, the maximum voltage V on/off on the pin is 13.5V 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 + ON/OFF Von/off - VO(+) LOAD VI(+) VO(-) VI(-) 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. Forced Load Sharing (Parallel Operation with -P option) For additional power requirements, the power module can be configured for parallel operation with forced load sharing. Good layout techniques should be observed for noise immunity when using multiple units in parallel. To implement forced load sharing, the following connections should be made: The share pins of all units in parallel must be connected together. The path of these connections should be as direct as possible. The on/off pins of all modules should also be tied together so that the modules are turned on and off at the same time. These modules do not block reverse current flow upon start-up, and can sink large currents from the energized output bus, which may cause other converters to reach their overcurrent limits, and/or exceed this module's device internal ratings. The use of OR'ing diodes or FETS to block reverse current flow is strongly encouraged to prevent module damage, or abnormal tripping of other parallel converters. When not using the parallel feature, leave the share pin open. The auto-restart option (4) is not available for modules with the parallel, -P, option. Figure 12. Remote On/Off Implementation. 8 LINEAGE POWER QBK033A0B Series Power Modules; DC-DC Converters 36 - 60 Vdc Input; 12Vdc Output; 33A Output Current Feature Descriptions (continued) Thermal Considerations The power modules operate in a variety of thermal environments and sufficient cooling should be provided to help ensure reliable operation. Thermal 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 temperature (TH). Peak temperature (TH) occurs at the position indicated in Figure 13. For reliable operation this temperature should not exceed the listed temperature threshold. delivered by each module in the respective orientation without exceeding the maximum TH temperature versus local ambient temperature (TA) for air flows of 1 m/s (200 ft./min), 2 m/s (400 ft./min) and 3 m/s (600 ft./min). The use of Figures 14 - 15 are shown in the following example: Example What is the minimum airflow necessary for a QBK033A0B operating at VI = 48 V, an output current of 16A, and a maximum ambient temperature of 70 C in transverse orientation.

Please refer to the Application Note "Thermal Characterization Process For Open-Frame BoardMounted Power Modules" for a detailed discussion of thermal aspects including maximum device temperatures.

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 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. Not all RoHS-compliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process. If additional information is needed, please consult with your Lineage Power representative for more details. Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. 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.
