Cost-effective DC-DC converter range in miniature case

20-01-2023 | RECOM Power | Power

RECOM has released a new family of surface-mount, cost-effective, regulated DC-DC converters designated R5M, R3M, R2M, and R1M, rated at 5W, 3W, 2W, and 1W, respectively. The parts provide a common case size of 13.2mm x 9.1mm footprint, 10.2mm high, with the R2M also offered in a through-hole DIP8 package. All parts function over a 4:1 input range of 9-36VDC or optionally 18-75VDC, whilst the R3M, R2M, and R1M range include 4.5-18V input. Single, fully regulated outputs provided are 3.3V, 5V, 9V, 12V, 15V, and 24V while dual outputs offered are +/-5V, +/-12V, and +/-15V.

The isolation rating for all parts is 1.6kV/1min, no minimum load is required, and continuous short circuit protection is incorporated together with an on/off control pin. Advanced circuit and thermal design results in high efficiency, peaking at 84%, enabling an operation to at least 100C ambient with derating and at full load up to 90C for the 1W part and 50C for the 5W part. The minimum temperature is -40C. EN 55032 EMC class A and B limits can be met with only a few external components, and reliability is high, for example, 8.5MHrs for the 1W part according to MIL-HDBK-217F, GB, 25C. For peace of mind, all parts are covered by the company's three-year warranty and are offered in tube packaging.

Matthew Dauterive, DC-DC product manager of RECOM, comments: “Our new wide input DC-DCs in a common format allow easy upgrade to a higher power as required and offer the convenience of surface mount terminations."
