Controller
The NCP1601 is a controller designed for Power Factor Correction
(PFC) boost circuits. The device operates in fixedfrequency
Discontinuous Conduction Mode (DCM) and variablefrequency
Critical Conduction Mode (CRM) and takes advantages from both
operating modes. DCM limits the maximum switching frequency. It
simplifies the frontended 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.
