Product Details

The PQ60025HPA80 PowerQor™ Peta half-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 maximum reliability. The Peta series converters offer industry leading output current for a standard “halfbrick” module. RoHS 5/6 Compliant (see page 13).

Operational Features

• Ultra-high efficiency, 90% half load, >87% full load
• Delivers up to 80 amps of output current with minimal derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V 100ms input voltage transient capability
• Fixed frequency switching provides predictable EMI performance

Mechanical Features

• Industry standard pin-out configuration
• Industry standard size: 2.3” x 2.4” (58.4 x 61.0mm)
• Total height only 0.45” (11.3mm), permits better airflow and smaller card pitch
• Total weight: 2.9 oz. (83 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, 30 MW input-to-output isolation
• UL 60950-1 recognized (US & Canada), basic insulation rating
• TUV certified to EN60950-1
• Meets 72/23/EEC and 93/68/EEC directives
• Meets UL94V-0 flammability requirements

Protection Features

• Input under-voltage lockout disables converter at low input voltage conditions
• Output current limit and short circuit protection>
• Active back bias limit prevents damage to converter from external load induced pre-bias
• Output over-voltage protection
• Thermal shutdown
