The RGA4W250W010A-003 is a 250W non-isolated buck converter with a 9 to 53V input range and a 3.3 to 40V adjustable output, housed in a 1/16th brick package measuring 35.6 x 25.6 x 13.0 mm excluding the mounting tab. It features negative logic remote on/off, remote sense, and includes optional power good, frequency synchronization, and output sequencing. The converter operates with a case temperature up to 110°C, is encased in a five-sided aluminum package for EMI improvement, and is qualified to MIL-STD-810G for shock and vibration. It supports conduction cooling, has an efficiency of up to 97.5%, and exceeds 12 million hours MTBF at 40°C ambient under full load. The part carries CE and UKCA markings and is backed by a three-year warranty.
DC-DC Converters, PCB mount type, Output: 250W, wide range (3.3 to 40V), 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.
