NCP1653PG ON Semiconductor

NCP1653, NCP1653A Controller, PFC, Continuous Conduction Mode, Fixed Frequency, Compact The NCP1653 is a controller designed for Continuous Conduction Mode (CCM) Power Factor Correction (PFC) boost circuits. It www.onsemi.com www.onsemi.com operates in the follower boost or constant output voltage in 67 or 100 kHz fixed switching frequency. Follower boost offers the benefits of MARKING DIAGRAMS reduction of output voltage and hence reduction in the size and cost of the inductor and power switch. Housed in a DIP8 or SO8 8 8 package, the circuit minimizes the number of external components NCP1653 NCP1653A 8 and drastically simplifies the CCM PFC implementation. It also AWL AWL 1 integrates high safety protection features. The NCP1653 is a driver YYWWG YYWWG PDIP8 for robust and compact PFC stages.
