Two-watt DC-DC converters in less than one-third of a square inch

The new 2W RTC2 series modules from Recom come in a six-pin SMD open-frame package with a footprint of less than one-third of a square inch. The 2:1 inputs voltage ranges of 4.5VDC to 9VDC or 18VDC to 36VDC can handle up to 15VDC and 50VDC respectively for up to 100ms. The converters are insulated up to 3kVDC/1s, and reach efficiencies over 80%. The 5V output versions will be the first to be launched on the market with additional outputs to be released at a later date. The modules are regulated at ±2% accuracy, with a tight line regulation of ±0.5% and load regulation of ±0.5%. They are short-circuit protected, and operate under natural convection at temperature ranges of -40C to +85C (24V version) without derating. The new modules comply with the RoHS guideline and are certified according to IEC/EN 62368-1 and EN 55022/24. The MTBF is more than 2,000 x 10³ hours at 25C according to MIL-HDBK 217F.
