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.
When Vcontrol is below this preset level Vctrl,FF, the NCP1602 (versions [B ] and [D ]) linearly decays the
