Product Details

The PQ60525HTA04 PowerQor® Tera converter is a nextgeneration, board-mountable, isolated, fixed switching frequency DC/DC converter that uses synchronous rectification to achieve extremely high conversion efficiency. The module is ideally suited to support the IEEE 802.3af standard for Power Over LAN and VoIP applications. 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, 92% at full rated load current
• Delivers up to 200 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

• 2250V, 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

Options

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 start-up sequence
• ORing FET drive supply for efficient ORing protection
