NCP1378 Overview
NCP1378 PWM Current- Mode Controller for Free- Running Quasi- Resonant Operation The NCP1378 bines a true current mode modulator and a demagnetization detector to ensure full borderline/critical Conduction Mode in any load/line conditions and minimum drain voltage switching (Quasi- Resonant operation). Due to its inherent skip cycle capability, the controller enters burst mode as soon as the power demand falls below...
