The SY22653 is a single stage non-isolated Flyback and PFC controller targeting at warm white and cold white LED color mixing and dimming application, which can achieve up to 5% dimming level, high precision for all loading range and different kinds of light color temperature.
It adopts the proprietary control architecture to achieve an accurate regulation of LED current and Quasi-Resonant valley turn-on high efficiency operation. Proprietary self-bias technique saves the bias supply and reduces the startup time. It keeps the converter in constant on time operation to achieve high power factor.
Reliable short/open LED protection is integrated.
