NCP1230D65R2G

Product Summary

The NCP1230D65R2G represents a major leap towards achieving low stand by power in mediu-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 (SOIC.8, SOIC.7, or PDIP.7), the NCP1230D65R2G contains all needed control functionality to build a rugged and efficient power supply. The NCP1230D65R2G is a current mode controller with internal ramp compensation. Among the unique features offered by the NCP1230D65R2G is an event management scheme that can disable the front-end PFC circuit during standby, thus reducing the no load power consumption. The NCP1230D65R2G itself goes into cycle skipping at light loads while limiting peak current (to 25% of nominal peak) so that no acoustic noise is generated. The NCP1230D65R2G has a high-voltage startup circuit that eliminates external components and reduces power consumption.
