Quar ter-brick The PQ300 33QGA30 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 PQ30 module offers a wide input voltage range to cover both 24V and 48V applications. 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. RoHS 5/6 Compliant (see page 12). Operational Features • High efficiency, 89.5%(24Vin); 88.5%(48Vin) at full rated load current • Delivers up to 30 amps of output current with minimal derating - no heatsink required • Wide input voltage range: 19V – 60V, with 80V 100ms input voltage transient capability • Fixed frequency switching provides predictable EMI performance • No minimum load requirement means no preload resistors required Mechanical Features • Industry standard quarter-brick pin-out configuration • Industry standard size: 1.45” x 2.3” (36.8x58.4mm) • Total height only 0.412” (10.46mm), 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 # PQ30033QGA30 PQ30033QGA30 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 Safety Features • 2000V, 30 MΩ input-to-output isolation provides input/output ground separation • UL/cUL 60950 recognized (US & Canada), basic insulation rating • TUV certified to EN60950 • 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
