DC-DC Converter

Product Details

The PQ24050QGA20 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.

Operational Features

• High efficiency, 87% at full rated load current
• Delivers up to 20 A of output current (100 W) 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

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
• UL 60950-1
• EN 60950-1

Protection Features

• Input under-voltage lockout disables converter at low input voltage conditions
• Output current limit and short circuit protection protects converter and load from damage
• Active back bias limit prevents damage to converter from external load induced pre-bias
• Output over-voltage protection
• Thermal shutdown
