JW1237 Adaptive 100/120Hz Current Ripple Remover With High Voltage MOSFET Integrated Parameters Subject to Change Without Notice DESCRIPTION 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 VIN pin to 31V.
Only one resistor is needed when the output voltage of AC/DC power is higher than 31V.
JW1237 allows user to setup maximum LED current by the sensing resistor between VS pin and GND, which protects JW1237 from being damaged when LED short co...
