Description

The TS19704 is a Primary-Side Control IC, high efficiency and simpler design with active power factor correction

especially for LED lighting applications. The IC achieves high power factor and low THD operation by

Discontinuous Conduction Mode (DCM) and constant on time. Precise constant current control regulates about

±3% accurate versus changes in input voltage and output voltage. TS19704 also provides gate driving voltage

clamping, Vcc overvoltage protection and system output open/short circuit protection to increase device

performance.
