NCP1230A - Low-Standby Power Soft Skip Mode Controller

General Description

Pin No.

1 PFC VCC This pin provides the bias voltage to the PFC controller.

Key Features

  • 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.

NCP1230A Low- Standby Power Soft Skip Mode Controller The NCP1230A represents a major leap towards achieving low standby power in medium--to--high power Switched--Mode Power Supplies such as notebook adapters, off--line battery chargers and consumer electronics equipment. Housed in a compact 8--pin package (SO--8 or PDIP--7), the NCP1230A contains all needed control functionality to build a rugged and efficient power supply. The NCP1230A is a current mode controller with internal ramp compensation. Among the unique features 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.
