PQ60120HTx14 DC-DC Converter










DC/DC Converter

Product Details

The PQ60120HTA14 PowerQor™ Tera converter is a next-generation, board-mountable, isolated, fixed switching frequency DC/DC converter that uses synchronous rectification toachieve 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 Tera series converters offer the maximum useable output current for any standard “half-brick” module. The Tera units also feature active current sharing for N+1 and parallel applications.

Operational Features

• Ultra-high efficiency, 93% at full rated load current
• Delivers up to 165 Watts of output power 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 half-brick pin-out configuration
• Industry standard size: 2.3” x 2.4” (58.4 x 61.0mm)
• Total height only 0.43” (11.2mm), permits better airflow and smaller card pitch
• Total weight: 2.6 oz. (75 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 MΩ input-to-output isolation
• UL/cUL 60950 recognized (US & Canada), basic insulation rating
• TUV certified to EN60950
• 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


Full Feature Modules
• Active current share for N+1 and parallel applications
• External Clock Synchronization pin for better EMI characteristics
• Startup Synchronization pin for more consistent startup sequence
• ORing FET drive supply for efficient ORing protection
