Description

The NJU7632 is a low voltage operation high-speed switching regulator control IC for step-down converter, with a standby function. It incorporates a totem pole output, which can drive an external MOS-FET easily. The NJU7632 also has a soft-start function, dead time control and timer latch for short circuit protection and their times are all adjustable with external parts. Further the internal standby function minimize the current during non-active condition. It is available in a small and thin 8-lead MSOP (TVSP) package, and it is suitable for battery powered applications.
