1 / 9 page TS19460 Taiwan Semiconductor Document Number: DS_P0000188 1 Version: D15 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 compensation or high-side current sensing. The output LED current accuracy is at ±5%, and it is equipped with current limit comparator 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 compatible signal. The output current can be programmed by an internal 250mV reference, or controlled externally through a 0~1.5V dimming input. The TS19460 is ideally suited for buck LED drivers and is requires only free external components (apart from the power stage) to produce a controlled LED current making it an ideal solution for low cost LED drivers. FEATURES ● Fast average current controller ● Programmable constant off-time switching ● Linear and PWM dimming capability ● Requires few external components for operation ● Output short circuit protection with skip mode ● Pin –compatible with TS19450CS APPLICATION ● DC/DC or AC/DC LED driver applications ● RGB backlighting LED driver ● Back lighting of flat panel displays ● General purpose constant current source ● Signage and decorative LED lighting ● LED street lighting SOP-8 Pin Definition: 1.
