JW1251O Controller for Adaptive 100/120Hz Current Ripple Removing Circuit
●DESCRIPTION
■JW®1251O 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 JW1251O ensures minimum power dissipation on NMOSFET while removing LED current ripple.
■Patented control strategies are optimized for dimmable solutions.
■JW1251O enables good ripple removing performance in the whole output current range and excellent system dynamic responding speed in the fast dimming.
■JW1251O provides short circuit protection and over temperature protection (OTP). OTP is trigged at 145℃, ripple current will be released with the temperature.
●FEATURES
■Controller for adaptive 100/120Hz current ripple remover
