PQ48120HGx12 DC-DC Converter








DC-DC Converter

Product Details

The PQ48120HGA12 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, >90% at full rated load current

Mechanical Features

• Industry standard pin-out configuration
• Industry standard size: 2.3” x 2.4” (58.4x61.0mm)
