http://onsemi.com

The NCP1601 is a controller designed for Power Factor Correction

(PFC) boost circuits. The device operates in fixed−frequency

Discontinuous Conduction Mode (DCM) and variable−frequency

Critical Conduction Mode (CRM) and takes advantages from both

operating modes. DCM limits the maximum switching frequency. It

simplifies the front−ended EMI filter design. CRM limits the

maximum currents of the boost stage diode, MOSFET and inductor.

It reduces the costs and improves the reliability of the circuit. This

device substantially exhibits unity power factor while operating in

DCM and CRM. The NCP1601 minimizes the required number of

external components. It incorporates high safety protection features

that make the NCP1601 suitable for robust and compact PFC stages.
