Step-Up / Flyback switching regulator IC with standby function
The NJU7602 is a low voltage operation high-speed switching regulator control IC for step-up and flyback converter,with a standby function. It incorporates a totem pole output,which can drive an external MOS-FET easily. The NJU7602 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 8-lead DMP and MSOP (TVSP) packages, and it is suitable for battery powered applications.
