Technical Specification Half 100 Amp, No Heatsink, Isolated DC/DC Converter The PQ60012HPAA0 PowerQor™ Peta 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 Peta series converters offer industry leading output current for a standard “half-brick” module. The Peta units also feature active current sharing for N+1 and parallel applications. Operational Features • Ultra-high efficiency, >88% half load, >83% full load • Delivers up to 100 amps of output current with minimal derating - no heatsink required • Wide input voltage range: 35V – 75V, with 100V 100ms input voltage transient withstand • Fixed frequency switching provides predictable EMI performance Mechanical Features • Industry standard pin-out configuration • Industry standard size: 2.3” x 2.4” • Total height only 0.43”, permits better airflow and smaller card pitch • Total weight: 2.9 oz. (83 grams) Safety Features • 2000V, 30 MΩ input-to-output isolation • UL 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 # PQ60012HPAA0 Protection Features • Input under-voltage lockout disables converter at low input voltage conditions • Output current limit and short circuit protection • Output over-voltage protection • Thermal shutdown 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 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 Doc.# 005-2HP621K Rev.
