General Description
The NJU7677 is a high-speed switching regulator control IC for PWM control step-up and fly-back converter that operates from 1.8V. It incorporates a totem pole driver output, which can directly drive an external MOS-FET. The NJU7677 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. It is available in a small and thin 8-lead MSOP (TVSP) package. It is suitable for battery powered applications.
