Description

The NJU7600 is a low voltage operation high-speed switching regulator control IC for PWM control step-up and fly-back converter.It incorporates a totem pole driver output, which can directly drive an external MOS-FET easily. The NJU7600 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 8-lead DMP, MSOP (TVSP) packages and 10-lead MSOP (TVSP) package. It is suitable for battery powered applications.
