DATA SHEET www.onsemi.com PWM Current-Mode Controller for Free Running Quasi-Resonant Operation NCP1207A, NCP1207B The NCP1207A/B 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.
