 SY28612 integrate a dimming interface converter whose input signal can be a 0/1~10V dimming signal, resistor, or PWM signal. It recognizes the signal automatically. The final output of SY28612 is a PWM signal which is used to control a dimmable CC regulator or drive an opto-coupler to achieve isolated dimming. The frequency of output PWM signal and the source current to drive passive 0~10V dimmer/Resistor can be set by external capacitor and resistor.

SY28612 integrates an LED current remover to eliminate low frequency current ripple, which is compatible with dimming. It adopts adaptive control scheme and no additional electrical design is needed.
