NCP1653: Controller, PFC, Continuous Conduction Mode, Fixed Frequency,
Compact
For complete documentation, see the data sheet
Product Description
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 voltage in 67 kHz (NCP1653A) or 100 kHz (NCP1653) fixed switching frequency. Follower
boost offers the benefits of reduction of output voltage and hence reduction in the size and cost of the inductor and power switch.
Housed in a DIP-8 or SO-8 package, the circuit minimizes the number of external components and drastically simplifies the CCM
PFC implementation. It also integrates high safety protection features. The NCP1653 is a driver for robust and compact PFC stages.
