Product Details

The PQ60018QML15 PowerQor® Mega quarter-brick converter is a next-generation, board-mountable, isolated, fixed switching frequency DC-DC converter that uses synchronous rectification to achieve very 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, yielding an extremely reliable product that is less than 8.5mm in height. The Mega series offer significant useable output current in an economical standard "quarter-brick" module.

Operational Features

• High efficiency, 80% at full rated load current
• Delivers up to 15 amps of output current with minimal derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V 100ms input voltage transient protection
• Fixed frequency switching provides predictable EMI performance
• No minimum load requirement means no preload resistors required

Mechanical Features

• Industry standard quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3”
• Total height only 8.5mm (0.335”), permits better airflow and smaller card pitch, meets NTT reqs.
• Total weight: 34 grams (1.2 oz.), 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

• 2000V, 10 MΩ input-to-output isolation provides input/output ground separation
• UL/cUL 60950 recognized (US & Canada), basic insulation rating
• TUV certified to EN60950
• 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
