Low Standby Power High Performance PWM Controller
FS6808DG
General Description
The FS6808DG 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. the FS6808DG contains all needed control functionality to build a rugged and efficient power supply. The FS6808DG is a current mode controller with internal ramp compensation. Among the unique features offered by the FS6808DG is an event management scheme that can disable the front−end PFC circuit during standby, thus reducing the no load power consumption. The FS6808DG itself goes into cycle skipping at light loads while limiting peak current so that no acoustic noise is generated.
