Description :

The NJU7680 is a high-speed low voltage operation switching regulator control IC. It features a totem pole driver that can directly drive an external MOS-FET.Each channel has an on/off switch. Therefore, the power sequence can be activated externally. Internal soft-start function, dead time control and timer latch function are included, and those functions can be easily controlled by external component.
