DC-DC Converter
The PQ24018QGx25 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, >84% at full rated load current
• Delivers up to 25 amps of output current with minimal derating
- no heatsink required
• Wide input voltage range: 18V - 36V meets or exceeds all 24V
bus standards
• Fixed frequency switching provides predictable EMI performance
• No minimum load requirement means no preload resistors required.

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 protects converer from abnormal
Mechanical Features
• Industry standard pin-out configuration
• Standard Size Open Frame:1.45" x 2.30" (36.8 x 58.4mm)
• Open Frame height: .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
