General 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.
