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 compact Switchmode Power Supplies.

Due to a novel concept, the circuit allows the implementation of a complete offline battery charger or a standby SMPS with few external components.

Furthermore, an integrated output short circuit protection lets the designer build an extremely low cost AC
