Pin No. end stage Pin Description This pin is a direct connection to the VCC pin (Pin 6) via a low impedance switch.

offered by the NCP1231 is an event management scheme that can disable the front.
end PFC circuit during standby, thus reducing the no load power consumption. The NCP1231 itself goes into cycle skipping at light loads while limiting peak current (to 25% of nominal peak) so that no acoustic noise is generated and while in the skip cycle mode. The NCP1231 also features an internal latching function that can be used for Overvoltage Protection (OVP). The latch is triggered when the voltage on.
