TS19450 Overview
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.
