NJU7691 Datasheet (NJR) - 300mA Synchronous Step-Down switching regulator IC

NJU7691, 300mA Synchronous Step-Down switching regulator IC

The NJU7691 is a synchronous rectification switching regulator IC with a power MOSFET (300mA output).

It incorporates an over-current detection and thermal shutdown circuit, which can make a power supply circuit with few external parts.

The output voltage can be set from 1.8V.

Therefore it is suitab
