BEI15 Series DC/DC Converters

BEI15 series isolated wide input bipolar 15-watt DC/DC converters from Murata Power Solutions offer minimal heat buildup and "no fan" operation

Image of Murata Power Solutions' BEI15 Series DC/DC Converters Murata Power Solutions' BEI-15 series features a full 15 watt output in one square inch of board area. This isolated DC/DC converter family offers efficient regulated DC power for PCB mounting. The wide range 4:1 inputs on the 0.96" x 1.1" x 0.35" (24.4 x 27.9 x 8.9 mm) converters are either 9 VDC to 36 VDC (Q12 models) or 18 VDC to 75 VDC (Q48 models), which is ideal for battery-powered and telecom equipment. The industry-standard pinout fits its larger 1" x 2" converters. Fixed output voltages of ±5 VDC, ±12 VDC or ±15 VDC are regulated to within ±0.25 percent. Applications include small instruments, area limited microcontrollers, data communications equipment, remote sensor systems, and vehicle and portable electronics.

The BEI-15 series includes full magnetic and optical isolation with basic protection up to 2250 VDC (Q48 models) and 2000 VDC (Q12 models). For powering digital systems, the outputs offer fast settling to step transients and will accept higher capacitive loads. Excellent ripple and noise specifications assure compatibility to noise-susceptible circuits. For systems requiring controlled startup/shutdown, an external remote On/Off control may use a switch, transistor, or digital logic. A wealth of self-protection features helps these devices avoid both converter and external circuit faults. These include input under voltage lockout and overtemperature shutdown. The outputs current limit using the “hiccup” auto restart technique and the outputs are short-circuit protected. Additional features include output over voltage and reverse conduction elimination. The high efficiency offers minimal heat buildup and “no fan” operation.
