Description
TS19705 is a primary-side-regulation with Fly-back control IC with active power factor correction function 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, V
CC
overvoltage protection and system output open/short
circuit protection to increase IC performance.
Features
● Constant Current Accuracy within <±3%
● Primary-Side Feedback Control
