Through-hole, 1/32nd brick-footprint, non-isolated dcs-dcs called the RPMA-4.5 and RPMA-8.0 carry 4.5-A and 8-A output ratings respectively. Each part has a wide 9-53-V input and trimmable, fully regulated output from 5-30 V (RPMA-4.5) or 3.3-16.5 V (RPMA-8.0). The cost-effective parts feature 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 4.5-A part of over 82M hours and over 31M hours for the 8-A part.
Each DC/DC is in the industry-standard open-frame 1/32nd brick format 19.1×23.4×9.6 mm 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.”
