DIO8650

Rev 1.2 DIO8650 Single Stage Flyback & PFC Controller With Primary Side Control For LED Lighting Features Primary side control eliminates the opto-coupler Valley turn-on of the primary MOSFET to achieve lower switching losses Power factor >0.95 @230VAC THD < 10% @230VAC Reliable short LED and Open LED protection Quick start up:<500ms Low start up current:15µA typical Package: SOT23-6, SOIC-8 Applications LED Lighting Descriptions The DIO8650 is a single stage Flyback and PFC controller targeting at LED lighting applications. The DIO8650 is a primary side controller without applying any secondary feedback circuit for low cost, and drives the Flyback converter in the quasi-resonant mode to achieve higher efficiency. The DIO8650 keeps the Flyback converter in constant on time operation to achieve high power factor. This chip adopts special design to achieve quick start up and reliable protection for safety requirement. Block Diagram www.dioo.com © 2016 DIOO MICROCIRCUITS CO., LTD D...
