NJU7601 Series
Step-Up/Flyback Switching Regulator IC with Power Saving PWM/PFM control
-
Description
The NJU7601 is a low voltage operation high-speed switching regulator control IC for step-up and fly-back converter, with PWM/PFM switching control. It can improve a switching efficiency on light load with automatically changing between PWM and PFM controls, and incorporates a totem pole output, which can drive an external MOS-FET easily. The NJU7601 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 and MSOP (TVSP) packages. It is suitable for battery powered applications.
