DC/DC Conver ter
The PQ40120QGA08 PowerQor® Giga quarter-brick converter is a next-generation, board-mountable, isolated, fixed switching frequency DC/DC converter that uses synchronous rectification to achieve extremely high conversion efficiency. The power dissipated by the converter is so low that a heatsink is not required, which saves cost, weight, height, and application effort. All of the power and control components are mounted to the multi-layer PCB substrate with highyield surface mount technology for greater reliability. The PQ40 module offers a wide input voltage range to cover both 24V and 48V applications. RoHS compliant (see page 13 ).
Operational Features
• High efficiency, 90% at full rated load current • Delivers up to 8.33 amps of output current (100W) with minimal derating - no heatsink required • Ultra wide input voltage range: 18V – 75V, with 100V 100ms input voltage transient capability • Fixed frequency switching provides predictable EMI performance • No minimum load requirement means no preload resistors required
PQ40120QGA08 Module
Pr otection Features
• Input under-voltage lockout disables converter at low input voltage conditions • Output current limit and short circuit protection protects converter and load from damage and consequent hazardous conditions • Active back bias limit prevents damage to converter from external load induced pre-bias • Output over-voltage protection protects load from damaging voltages • Thermal shutdown protects converter from abnormal environmental conditions
Mechanical Features
• Industry standard quarter-brick pin-out configuration • Industry standard size: 1.45” x 2.3” (36.8x58.4mm) • Total height only 0.43” (10.9mm), permits better airflow and smaller card pitch • Total weight: 1.2 oz. (34 grams) • Flanged pins designed to permit surface mount soldering (avoid wave solder) using FPiP technique
Safety Features
• 2000V, 30 MW input-to-output isolation provides input/output ground separation • UL/cUL 60950-1 recognized (US & Canada), basic insulation rating • TUV certified to EN60950-1 • Meets 72/23/EEC and 93/68/EEC directives which facilitates CE Marking in user’s end product • Board and plastic components meet UL94V-0 flammability requirements
Contr ol Features
• On/Off control referenced to input side (positive and negative logic options are available) • Remote sense for the output voltage compensates for output distribution drops • Output voltage trim permits custom voltages and voltage margining

1) Pins 1-3, 5-7 are 0.040” (1.02mm) diameter with 0.080” (2.03 mm) diameter standoff shoulders. 2) Pins 4 and 8 are 0.062” (1.57 mm) diameter with 0.100” (2.54 mm) diameter standoff shoulders. 3) Other pin extension lengths available. Recommended pin length is 0.03” (0.76mm) greater than the PCB thickness. 4) All Pins: Material - Copper Alloy; Finish - Matte Tin over Nickel plate 5) Undimensioned components shown are for visual reference only. 6) Weight: 1.2 oz. (34 g) 7) All dimensions in inches (mm) Tolerances: x.xx +/-0.02 in. (x.x +/-0.5mm) x.xxx +/-0.010 in. (x.xx +/-0.25mm) 8) Workmanship: Meets or exceeds IPC-A-610C Class II 9) UL/TUV standards require a clearance greater than 0.04” (1.02mm) between input and output for Basic insulation. This issue should be considered if any copper traces are on the top side of the user’s board. Note that the ferrite cores are considered part of the input/primary circuit. 10) The flanged pins are designed to permit surface mount soldering (allowing to avoid the wave soldering process) through the use of the flanged pin-in-paste technique.
