TS19460 - AC/DC WLED Driver

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.

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.

TS19460 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 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.
