Typical Application for NCP1200 PWM Current-Mode Controller for Low-Power Universal Off-Line Supplies for AC-DC wall adapter showing the reduced part count due to the NCP1200

Typical Application for NCP1200 PWM Current-Mode Controller for Low-Power Universal Off-Line Supplies for AC-DC wall adapter showing the reduced part count due to the NCP1200. 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
