DIO8105

Rev 0.2 DIO8105 Single Stage Flyback & PFC Controller with PSR CV Control For LED Lighting Features Primary side CV control eliminates the opto-couple. Valley turn-on of the primary MOSFET to achieve low switching losses Internal high current MOSFET driver: 0.15A sourcing and 0.5A sinking Power factor >0.9 @230VAC Reliable protection: SCP, OCP, OTP & OVP Quick start up:<500ms Built-in Soft Start Low start up current:10μA typical Package: SOT23-6, SOIC-8 Applications AC/DC adapters LED Lighting Descriptions DIO8105 is a single stage Flyback and PFC controller targeting at Constant Voltage (CV) applications. The DIO8105 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 DIO8105 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 safe...
