In standby and during the.
offered by the NCP1230A is an event management scheme that can disable the front--end PFC circuit during standby, thus reducing the no load power consumption. The NCP1230A itself goes into soft skipping at light loads while limiting peak current (to 25% of nominal peak) so that no acoustic noise is generated. The NCP1230A has a high--voltage startup circuit that eliminates external components and reduces power consumption. The NCP1230A also features an internal latching function that can be used for OVP protection. This latch is triggered by pulling the CS pin above 3.0 V and can only be reset.
