NCP1653 - Continuous Conduction Mode PFC Controller

Pin Symbol Name Function 1 FB / SD Feedback / This pin receives a feedback current IFB which is proportional to the PFC circuit output voltage.

Shutdown The current is for output regulation, output overvoltage protection (OVP), and output undervoltage protection (UVP).

When IFB goes above 10

NCP1653, NCP1653A Compact, 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 the inductor and power switch.

Housed in a DIP 8 or SO 8 packa
