NCP1207 Overview
NCP1207 PWM Current−Mode Controller for Free Running Quasi−Resonant Operation The NCP1207 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 a...
