NJU7691

300mA Synchronous Step-Down switching regulator IC

■GENERAL DESCRIPTION

■PACKAGE OUTLINE

The NJU7691 is a synchronous rectification type switching

regulator IC with a power MOSFET (300mA output).

It has an over current detection and an overheat protection

circuit. Therefore, the circuit can be configured with few

external parts.

NJU7691RB1

The output voltage can be set from 0.8V. It is suitable for

supplying power to a digital chip and a logic IC with low

voltage.
