Product Details

The PQ60240EGL03 PowerQor® Giga eighth-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 interfaces, it is extremely reliable. RoHS complaint, see last the page.

Operational Features

• High efficiency >90% at full rated load current
• Delivers up to 3 amps of output current (72W) 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
• No minimum load requirement means no preload resistors required

Mechanical Features

• Industry standard eighth-brick pin-out configuration
• Industry standard size: 0.90” x 2.3” (22.9x58.4mm)
• Total height only 0.349" (8.9mm), permits better airflow and smaller card pitch
• Total weight: 0.68 oz. (19 grams)
• Flanged pins designed to permit surface mount soldering (avoid wave solder) using FPiP technique

Control Features

• On/Off control referenced to input side (pos & neg logic options available)
• Remote sense for the output voltage compensates for output distribution drops
• Output voltage trim permits custom voltages and voltage margining

Safety Features

• CAN/CSA C22.2 No. 60950-1
• UL 60950-1
• EN 60950-1

Protection Features

• Input under-voltage lockout disables converter at low Vin conditions
• Output current limit and short circuit protection protects converter and load from permanent damage and consequent hazardous
conditions
• Active back bias limit prevents damage to converter from external load induced pre-bias
• Output over-voltage protection protects load from damaging voltages
• Thermal shutdown protects converter from abnormal environmental conditions
