The BEI15 series of isolated, wide input bipolar DC/DC converters from Murata Power Solutions offers a small footprint solution for high current applications in mobile and battery powered products, test equipment and telecoms and wireless designs. The new 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 0.96in. (24.4mm) x 1.1in. (27.9mm) x 0.35in. (8.9mm) and an operating temperature range of -40°C to +85°C. Excellent ripple and noise specifications assure compatibility to noise susceptible circuits, and fast settling outputs that accept higher capacitive loads make the BEI15 series ideal for powering digital systems.
Self-protection features that avoid both converter and external circuit faults include input undervoltage lockout and overtemperature shutdown. The module outputs current limit using the ‘hiccup’ auto restart technique and are short-circuit protected. Additional features include output overvoltage and reverse conduction elimination.
Fully compliant with RoHS-6 standards, the BEI15 series also meets UL/EN/IEC 60950-1 safety approvals.
