1200P100 PWM Current-Mode Controller DIP-8

Product details of 1200P100 PWM Current-Mode Controller DIP-8
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 to ward ultra−compact Switchmode Power Supplies. Due to a novel concept, the circuit allows the implementation of a co mplete offline battery charger or a stand by SMPS with few external components. Furthermore, an integrated output shor t−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, 6 0 kHz or 100 kHz, the cont .
