NJU7601 - JRC

NJU7601 Step-Up/Flyback Switching Regulator IC

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 ha.
