GENERAL DESCRIPTION
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. The FS6808DG has a high−voltage (500V) startup circuit that eliminates external components and reduces power consumption. The FS6808DG also features an internal latching function that can be used for OVP protection. True overload protection, internal 2.5 ms soft−start, internal leading edge blanking, internal frequency dithering for low EMI are some of the other important features offered by the FS6808DG. offered in SOP-8 package.FEATURES
