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 safety requirement.
•Primary side CV control eliminates the optocouple.
