Description
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 suitable for a power supply circuit for digital chips and logic ICs. The NJU7691 is available in a small and thin 8-lead MSOP (TVSP) package.
