PQ60033QML15PNS

Technical Specification Quarter Brick 48Vin 3.3Vout 15A 15 Amp, No Heatsink, Isolated DC/DC Converter The PQ60033QML15 PowerQor™ Mega quarterbrick converter is a next-generation, board-mountable, isolated, fixed switching frequency DC/DC converter that uses synchronous rectification to achieve very 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, yielding an extremely reliable product that is less than 8.5mm in height. The Mega series offer significant useable output current in an economical standard “quarter-brick” module. PQ60033QML15 Module Operational Features • High efficiency, >86% at full rated load current • Delivers up to 15 amps of output current with minimal derating - no heatsink required • Wide input voltage range: 35V – 75V, with 100V 100ms input voltage transient protection • Fixed frequency switching provides predictable EMI performance • No minimum load requirement means no preload resistors required Protection Features • Input under-voltage lockout disables converter at low input voltage conditions • Output current limit and short circuit protection protects converter from excessive load current or short circuits • 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” • Total height only 8.5mm (0.335”), permits better airflow and smaller card pitch, meets NTT reqs. • Total weight: 34 grams (1.2 oz.), lower mass greatly reduces vibration and shock problems Safety Features • 2000V, 10 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 Control 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 # PQ60033QML15 Phone 1-888-567-9596 Doc.# 005-2QM633E Rev.
