TS19450 Datasheet (Taiwan Semiconductor)

TS19450, AC/DC WLED Driver

The TS19450 is an open loop, current mode control LED driver IC.

It can be programmed to operate in either a constant frequency or constant off-time mode.

It includes an 8V~450V linear regulator which allows it to work from a wide range of input voltages without the need for an external low voltage

TS19450 Features

* Switch mode controller for single switch LED drivers

* Open loop peak current controller

* Internal 8V~450V linear regulator

* Constant frequency or constant off-time operation

* Linear and PWM dimming capability

* Requires few external components for operation APPLICATION
