Murata Power Solutions BEI15 Isolated Bipolar 15W DC/DC Converters

Murata Power Solutions BEI15 Isolated Bipolar 15 Watt DC/DC Converters

Murata Power Solutions BEI15 Isolated Bipolar 15W DC/DC Converters feature a full 15W output in one square inch of board area, the BEI-15 series isolated DC/DC converter family offers efficient regulated DC power for printed circuit board mounting. The BEI-15 series includes full magnetic and optical isolation with basic protection up to 2250VDC (Q48 models) and 2000VDC (Q12 models). For powering digital systems, the outputs offer fast settling to step transients and will accept higher capacitive loads. The excellent ripple and noise specifications assure compatibility to noise-susceptible circuits and for systems requiring controlled startup/shutdown, an external remote on/off control may use a switch, transistor or digital logic.

These DC/DC converters come with a wealth of self-protection features that avoid both converter and external circuit faults. These include input undervoltage lockout and over-temperature shutdown. The outputs current limit using the hiccup auto-restart technique and the outputs are short-circuit protected. Typical applications include small instruments, area-limited microcontrollers, data communications equipment, and remote sensor systems.
