ON Semiconductor NCP1200 PWM Current-Mode Controller Datasheet
The NCP1200 is a PWM Current-Mode Controller designed for low-power universal off-line supplies. It operates at fixed frequencies of 40 kHz, 60 kHz, or 100 kHz and drives low gate-charge switching devices like IGBTs or MOSFETs. The device features an internal structure that allows operation without an auxiliary winding by self-supplying from the DC rail.
