Product Details

The PQ48015HGA40 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.

Operational Features

• Ultra-high efficiency, 84% at full rated load current
• Delivers up to 40 amps of output current 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

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

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
