Product Details

The PQ24033QGA25 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. RoHS Compliant see last page.

Operational Features

• High efficiency, 87% at full rated load current
• Delivers up to 25 A of output current with minimal derating
- no heatsink required
• Wide input voltage range: 18-36 V meets or exceeds all 24 V bus standards
• Fixed frequency switching provides predictable EMI performance
• No minimum load requirement means no preload resistors required.

Mechanical Features

• Industry standard pin-out configuration
• Standard Size Open Frame:1.45" x 2.30" (36.8 x 58.4mm)
• Open Frame height: 0.40” (10.2mm),
• Open Frame Weight: 1.2 oz. (34g)
• Flanged pins designed to permit surface mount soldering (avoid wave solder) using FPiP technique on Open Frame Units

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

• CAN/CSA C22.2 No. 60950-1

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 protectsconverer from abnormal environmental conditions
