Technical S pecification PQ40033QGA25 18-75V Input I nput 3.3V Output 25Amp Current 2000Vdc Isolation Quar t er-brick ter-brick DC/DC Conver ter The PQ400 33QGA25 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 high-yield 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 12 ). Operational Features • High efficiency, 88.5% at full rated load current • Delivers up to 25 amps of output current (82W) 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 PQ40033QGA25 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 permanent 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 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 Product # PQ40033QGA25 Phone 1-888-567-9596 www.synqor.com • 2000V, 30 MΩ 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 Safety Features Doc.# 005-2QG333D Rev.
