NCP1200 PWM Current-Mode Controller for Low-Power Universal Off-Line Supplies Housed in SOIC- 8 or PDIP- 8 package, the NCP1200 represents a major leap toward ultra- pact Switchmode Power Supplies. Due to a novel concept, the circuit allows the implementation of a plete offline battery charger or a standby SMPS with few external ponents. Furthermore, an integrated output short- circuit protection lets the designer build an extremely low- cost AC- DC wall adapter associated with a simplified feedback scheme. With an internal structure operating at a fixed 40 kHz, 60 kHz or 100 kHz, the controller drives low gate- charge switching devices like an IGBT or a MOSFET thus requiring a very...
