Isolated DC-DC converter series delivers 4:1 input range in compact SMT package

CUI has announced the addition of a new 3W isolated DC-DC converter series to its portfolio of low power DC-DC converters.) The PQME3 series housed in a compact, industry standard 14 pin surface mount package measuring 19.2mm x 18.1mm x 10.16mm), provides a rugged, low power solution for a variety of industrial, test and measurement, and telecommunication applications, thanks to its encapsulated design. Ideal for converting and isolating fluctuating dc voltages, the series features 4:1 input ratio ranges of 9VDC to 36VDC and 18VDC to 75VDC, single regulated outputs of 3.3VDC, 5VDC, 9VDC, 12VDC, 15VDC, and 24VDC, remote on/off control, and 1500VDC input to output isolation. For devices where energy consumption is a concern, the series offers efficiency up to 84% and no-load power draw less than 0.1W. Operating temperatures range from -40C up to +71C at full load, derating to 60% load at +85C, making the low power modules suitable for harsh environments. The converters also meet CISPR22/EN55022 Class B limits for conducted and radiated emissions, while carrying over current and short circuit protections as well as a minimum MTBF of 1,000,000 hours at +25C ambient, calculated per MIL-HDBK-217F.
