The SY22627 is a high efficiency dimmable LED regulator for 12V halogen lamp-replacement market. It operates over a very wide input voltage range from 4V to 36V and integrates a very low RDS(ON) power switch for boost stage to minimize the conduction loss. A built-in current ripple remover is used to simplify the design for cost down.

The current hysteresis control scheme of boost and current ripple remover are used to improve the electronic transformer compatibility and dimmer compatibility.
