TS19460 Datasheet | Taiwan Semiconductor

Taiwan Semiconductor AC/DC WLED Driver with Average-Mode Constant Current Control DESCRIPTION The TS19460 is an average current mode control LED driver IC operating in a constant off-time mode. It greatly improves accuracy, line and load regulation of the LED current without any need for loop pensation or high-side current sensing. The output LED current accuracy is at ±5%, and it is equipped with current limit parator for hiccup mode output short circuit protection. The TS19460 can be powered from an 8V~450V supply. A PWM dimming input is provided that accepts an external control TTL patible signal. The output current can be programmed by an internal 250mV reference, or...
