Wide input regulated DC/DCs with 1W to 5W rating in common miniature case size
Jan 18, 2023
Users can now take advantage of surface mount technology with our new R5M, R3M, R2M, and R1M regulated DC/DC converters, rated at 5W, 3W, 2W, and 1W respectively.
The family shares a common case size of 13.2mm x 9.1mm footprint, 10.2mm high, with the R2M additionally available in a through-hole DIP8 package. The DC/DCs operate over a 4:1 input range, 9-36VDC or 18-75VDC, while the R3M, R2M, and R1M range additionally include 4.5-18V input. Outputs available are fully regulated: single 3.3V, 5V, 9V, 12V, 15V, or 24V, and dual +/-5V, +/-12V, or +/-15V.
The DC/DCs feature on/off control and are protected against short circuits while advanced thermal and circuit design has resulted in high efficiency, allowing an operation to at least 100°C with derating. At the same time, the parts operate to usefully high temperatures at full load, for example, to 90°C for the 1W R1M part. No minimum load is required.
All parts feature a 1.6kV/1min isolation rating and EN55032 class A and B EMC limits can be met with a simple external filter. Reliability calculated to MIL-HDBK 217F, GB at 25°C is high, for example 8.5MHrs for the R1M 1W part.
