Murata Power Solutions UWE Series DC/DC Converters

Murata Power Solutions UWE Series DC/DC Converters are open-frame, low-profile E-bricks that fit the industry-standard quarter-brick footprint. These converters employ an interleaved, synchronous-rectifier topology that exploits 100% of their duty cycle and simultaneously achieves high efficiency, low noise, tight line/load regulation, and quick step response.The converters have an open-frame design, high efficiency, low-on-resistance FETs, and planar magnetics embedded in heavy-copper PC boards that contribute to impressive thermal derating. These converters' feature set includes high isolation (2250Vdc, 48V models), input pi filters, input under-voltage shutdown, output overvoltage protection, current limiting, short-circuit protection, and thermal shutdown. The standard footprint carries VOUT trim, on/off control, and sense pins (sense pins are not available on 12V or higher models).
