18-11-2021 | Recom International | Power

RECOM now provides 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 offers 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 provide very high efficiency, peaking at 98%, enabling fully-rated load operation to +60C with convection cooling only and +85C with derating/airflow, dependant on input/output conditions. On/off control is incorporated together with remote output sensing. The devices are fully protected against input undervoltage, output over current, short circuit and over temperature. Operation reliability is also high, with an MTBF for the 4.5A part of over 82M hours and over 31M hours for the 8A part.

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

Matthew Dauterive, DC-DC product manager, 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.”
