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 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.
