JW1237 Adaptive 100/120Hz Current Ripple Remover

JW1237, integrated with 150V NMOSFET, is used to drive a LED string, and remove the 100/120Hz LED current ripple on AC/DC power by a capacitor between VC and GND. The adaptive technology ensures minimum power dissipation on JW1237 while removing LED current ripple. JW1237 clamps the input voltage on.
