NJU7680
2ch switching regulator IC
■GENERAL 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.
