PQ48150HGA10PRF

Technical Specification Brick Half 48Vin 15Vout 10A 150 Watt, No Heatsink, Isolated DC/DC Converter The PQ48150HGA10 PowerQor™ Giga 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. The Giga series converters offer enhanced useable output current in a standard “half-brick” module. The Giga units also feature active current sharing for N+1 and parallel applications. PQ48150HGA10 Module Operational Features • Ultra-high efficiency, 92% at full rated load current • Delivers up to 150 watts of output power with minimal derating - no heatsink required • Wide input voltage range: 35V – 75V meets or exceeds all 48V bus standards • Fixed frequency switching provides predictable EMI performance Protection Features • Input under-voltage lockout and over-voltage shutdown protects against abnormal input voltages • Output current limit and short circuit protection • Output over-voltage protection • Thermal shutdown Mechanical Features • Industry standard pin-out configuration • Industry standard size: 2.3” x 2.4” • Total height only 0.40”, permits better airflow and smaller card pitch • Total weight: 2.1 oz. (59 grams) 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 Safety Features • 2000V, 10 MΩ input-to-output isolation • UL/cUL 60950 recognized (US & Canada), basic insulation rating • TUV certified to EN60950 • Meets 72/23/EEC and 93/68/EEC directives • Meets UL94V-0 flammability requirements Product # PQ48150HGA10 Phone 1-888-567-9596 Optional Features (Full-Feature modules) • Active current share for N+1 and parallel applications • External Clock Synchronization pin for better EMI characteristics • Startup Synchronization pin for more consistent startup sequence • ORing FET drive supply for efficient ORing protection Doc.# 005-2HG415C Rev.
