SY5830 Datasheet (Silergy) - Single Stage Flyback And PFC Controller

SY5830, Single Stage Flyback And PFC Controller

The SY5830 is a single stage Flyback and PFC controller targeting at LED lighting applications.

It 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.

It keeps the Flyback
