SY5802
Overview
The SY5802 is a single stage Flyback and PFC controller targeting at LED lighting applications with PWM/Analog dimming. It is a primary side controller without applying any secondary feedback circuit for low cost, and drives the Flyback converter in the quasiresonant mode to achieve higher efficiency.
- Primary side control eliminates the opto-coupler.
- PWM or Analog Dimming.
- Valley turn-on of the primary MOSFET to achieve low switching losses
- 0.3V primary current sense reference voltage leads to
