                                      SY5803 - Single stage Buck-Boost PFC controller

                                      Features

                                      • Valley turn-on of the MOSFET to achieve low switching losses
                                      • Aux-winding for ZCS detection and bias current optional
                                      • 0.3V current sense reference voltage leads to a lower sense resistance thus a lower conduction loss
                                      • Internal high current MOSFET driver: 1A  sourcing and 2A sinking
                                      • Low start up current: 15µA typical
                                      • Reliable short LED and Open LED protection
                                      • Power factor >0.90 with single-stage conversion
                                      • Compact package: SO8

                                      Typical Application



                                      Description

                                      The SY5803 is a single stage Buck-Boost PFC controller targeting at LED lighting applications. It drives the Buck-Boost converter in the quasi-resonant mode to achieve higher efficiency. It keeps the Buck-Boost converter in constant on time operation to achieve high power factor.

                                      Applications

                                      • LED lighting
                                      • Down light
                                      • Tube lamp
                                      • PAR lamp
                                      • Bulb lamp
