Smyrna, Ga.The BEI15 series of isolated, wide input bipolar DC/DC converters from Murata Power Solutions offers a small footprint for high-current applications in mobile and battery powered products, test equipment and telecom and wireless designs.
The BEI15 series modules deliver a full 15W of output power with efficiency levels up to 86% from one square inch of board area and can provide a space-saving, pin compatible, drop-in replacement for older, 1in. x 2in. DC/DC converters.
The through-hole PCB mounting BEI15 series offers a choice of ± 5V, ±12V and ±15V bipolar output voltages regulated to within ±0.25%. Designers can choose from wide 4:1 input voltages of either 9-36V (with positive remote on/off polarity), or 18-75V (with negative remote on/off polarity). All modules have full magnetic and optical isolation with basic protection up to 2250VDC. A synchronous rectifier forward topology is used to achieve high levels of efficiency that allow no-fan operation.
The low-profile open-frame package has overall dimensions of 0.96-in. (24.4-mm) x 1.1-in. (27.9-mm) x 0.35-in. (8.9-mm) and an operating temperature range of -40°C to +85°C.
Pricing: Starts at $17 in OEM quantities.
