Product Details
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.
