DC-DC Converter

Product Details

The PQ60050QGA20 PowerQor® Giga quarter‑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. Since the PowerQor converter has no explicit thermal connections, it is extremely reliable.

Operational Features

• High efficiency, >89% at full rated load current
• Delivers up to 20 A of output current (100 W) with minimal derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V 100 ms input voltage transient withstand
• Fixed frequency switching provides predictable EMI performance
• No minimum load requirement means no preload resistors required
• See the Baseplate Addendum web page for more options.

Mechanical Features

• Industry standard quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3”
• Total height less than 0.40”, permits better airflow and smaller card pitch
• Total weight: 1.2 oz (34 g), lower mass greatly reduces vibration and shock problems

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

• 2000 V, 10 MΩ input-to-output isolation provides input/output ground separation
• UL/cUL 60950-1 recognized (US & Canada), basic insulation rating
• TUV certified to EN60950-1
• Meets 72/23/EEC and 93/68/EEC directives which facilitates CE Marking in user’s end product
• Board and plastic components meet UL94V-0 flammability requirements

Protection Features

• Input under-voltage lockout disables converter at low input voltage conditions
• Output current limit and short circuit protection protects converter from excessive load current or short circuits
• Output over-voltage protection protects load from damaging voltages
• Thermal shutdown protects converter from abnormal environmental conditions
