Single Stage Flyback or Buck-Boost Current Control with Active PFC for LED lighting
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). The line and load regulation of LED current is about <±3% because of particular control method. TS19705 also provides gate driving voltage clamping, VCC overvoltage...
