The RGA4W250W020A-003 is a 250W non-isolated DC-DC buck converter in a 1/16th brick package, measuring 35.6 x 25.6 x 13.0 mm excluding the mounting tab. It accepts a 9 to 53 VDC input and provides a 3.3 to 15 VDC adjustable output with up to 20 A current. The module is encapsulated in a five-sided aluminum case, rated for operation up to 110°C case temperature, and qualified to MIL-STD-810G for shock and vibration. It supports conduction cooling, remote on/off with negative logic, and includes optional power good, frequency synchronization, and output sequencing features. Efficiency ranges from 90% to 97%, with a switching frequency of 400 kHz. The part meets CE and UKCA safety standards and carries a three-year warranty.
DC-DC Converters, PCB mount type, Output: 250W, wide range (3.3 to 15V), Non-Isolated Step-down
The rugged RGA non-isolated DC-DC step-down converters are encapsulated in a five-sided aluminium case and rated for up to 110˚C operation. The modules have the industry standard 1/16th brick pin-out, are qualified to high shock and vibration and designed for fan-less, conduction cooled applications. The series accepts a wide input range to support multiple DC bus and battery voltages. Standard and optional features include remote on/off, remote sense, power good, frequency synchronization and output sequencing, making the modules a truly versatile power solution. The wide output adjustment range allows one model to be used in multiple positions, assisting inventory and part number reduction.
