NCP1653A Description
NCP1653, NCP1653A pact, Fixed-Frequency, Continuous Conduction Mode PFC Controller The NCP1653 is a controller designed for Continuous Conduction Mode (CCM) Power Factor Correction (PFC) boost circuits. It operates in the follower boost or constant output voltage in 67 or 100 kHz fixed switching frequency. Follower boost offers the benefits of reduction of output voltage and hence reduction in the size and cost of...
