TS19450 Datasheet AC/DC WLED Driver

Manufacturer: Taiwan Semiconductor

General Description

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 supply.
