The SY5882S is a DC/DC Flyback controller targeting at LED Dimming applications, which can achieve up to 2.5% dimming level and high precision for all loading range. It adapts to a wide range of output voltage applications and has good load regulation. It is a primary side controller without applying any secondary feedback circuit for low cost, and drives the converter in the quasiresonant mode to achieve higher efficiency. It keeps the converter in peak current control to achieve low power frequency ripple.
