NJU7640 Datasheet (JRC) - Step-Down switching regulator IC

NJU7640, Step-Down switching regulator IC

The NJU7640 is a low voltage operation high-speed switching regulator control IC for step-down converter, with a pulse-by-pulse over-current protection.

The pulse-by-pulse over-current protection circuit can limit the over current in switching operation.

It incorporates a totem pole output, which ca
