NCP1308 - PWM Current Mode Controller
NCP1308 PWM Current-Mode Controller for Free-Running Quasi-Resonant Operation The NCP1308 combines 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 predetermined level.
As this happens at low peak current, no audible noise can
