Product Summary

The 1653A is a controller designed for Continuous Conduction Mode (CCM) Power Factor Correction (PFC) boost circuits. The 1653A operates in the follower boost or constant output voltage in 67 or 100kHz 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. The 1653A minimizes the number of external components and drastically simplifies the CCM PFC implementation. The 1653A also integrates high safety protection features. The 1653A is a driver for robust and compact PFC stages.
