NCP1602 Description
NCP1602 Enhanced, High-Efficiency Power Factor Controller The 6−pin PFC controller NCP1602 is designed to drive PFC boost stages. It is based on an innovative Valley Synchronized Frequency Fold−back (VSFF) method. In this mode, the circuit classically operates in Critical conduction Mode (CrM) when Vcontrol voltage exceeds a programmable value Vctrl,FF.
