NCP1622 High-Efficiency Power Factor Controller

Pin Number Name Function 1 VCTRL The error amplifier output is available on this pin. The network connected between this pin and ground adjusts the regulation loop bandwidth that is typically set below 20 Hz to .

DATA SHEET www.onsemi.com Enhanced, High-Efficiency Power Factor Controller NCP1622 TSOP 6 SN SUFFIX 1 CASE 318G The 6 pin PFC controller NCP1622 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 NCP1.
