JW1221A Controller for Adaptive 100/120Hz Current Ripple Removing Circuit

JW1221A is a controller for driving external NMOSFET to remove the 100/120Hz LED current ripple on AC/DC power by a capacitor between VC and GND. The adaptive technology of JW1221A ensures minimum power dissipation on NMOSFET while removing LED current ripple. JW1221A clamps the input voltage on VIN.
