Highly efficient wide-input DC/DCs in 1/32nd bricks

RECOM now offers through-hole, 1/32nd brick-footprint, non-isolated DC/DCs - the RPMA-4.5 and RPMA-8.0, with 4.5A and 8A output ratings respectively. Each part has a wide 9-53V input and trimmable, fully regulated output from 5-30V (RPMA-4.5) or 3.3-16.5V (RPMA-8.0). The cost-effective parts feature very high efficiency, peaking at 98%, allowing fully-rated load operation to +60°C with convection cooling only and to +85°C with derating/airflow, depending on input/output conditions. On/off control is included along with remote output sensing. The RPMA-4.5 and RPMA-8.0 are fully protected against input undervoltage, output over current, short circuit and over temperature. Reliability in operation is also high with an MTBF for the 4.5A part of over 82M hours and over 31M hours for the 8A part.

Each DC/DC is in the industry standard open-frame 1/32nd brick format 19.1 x 23.4 x 9.6mm providing an ultra-compact solution for high power operation.

Matthew Dauterive, DC/DC Product Manager of RECOM comments, “These DC/DCs are a really cost effective and efficient way to provide non-isolated regulated power from a wide-range input. They will find use in a wide variety of markets, from industrial to test and measurement, telecom, and medical.”
