TS19705CX6 Description
TS19705 is constant current control IC with active power factor correction isolated or non-isolated AC-DC LED lighting control. The TS19705 is configurable as an isolated, primary-side-regulated Flyback controller or non-isolated Buck-Boost converter for LED lighting applications. The IC achieves high power factor and low Total Harmonic Distortion (THD) operation by Boundary Conduction Mode (BCM).
