TS19705CX6
Taiwan Semiconductor
1 Version: C1607
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, V
CC
overvoltage protection
and system output open/short circuit protection to
increase IC performance.

Note:
1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the operational
sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may
remain possibility to affect device reliability.
2. Devices are ESD sensitive. Handing precaution recommended.
3. Thermal Resistance is specified with the component mounted on a low effective thermal conductivity test board in free air at
T
