JW1210 Overview
JW1210 is used to drive a LED string (<60V), and remove the 100/120Hz current ripple on AC/DC power by a capacitor between VC and GND. JW1210 allows user to setup the maximum voltage on LED pin by connect a resistor between VLMT and GND. If the voltage on LED pin exceeds limit threshold, the current ripple remover is disabled and remain the LED voltage, which could help limiting the power dissipation on chip.
