MEF1 Isolated 1W Single Output DC/DC Converters

Murata Power Solutions MEF1 Isolated 1W Regulated Single Output DC/DC Converters are used where a tightly regulated supply is required by offering an output regulation of <1%. The MEF1 components are fully encapsulated with toroidal magnetics in an SMD-constructed package with through hole mounting and short-circuit protection. The single rail regulated output makes them an ideal choice for power sensors; such as pressure transducers, hall effect sensors, and mass air-flow sensors.
