The TS19320CS is a phase-cut (TRIAC) dimmable constant current control IC with active
power factor correction isolated or non-isolated AC-DC LED lighting control. The
TS19320CS is configurable as an isolated, primary-side-regulated Flyback controller or
non-isolated Buck-Boost converter. It is compatible with many types of TRIAC dimmers
including leading-edge and trailing-edge. The IC achieves a high power factor and low
total harmonic distortion (THD) and guarantees constant current accuracy to <±5%
using Boundary Conduction Mode (BCM) operation. The TS19320CS has built-in
protection circuits such as gate voltage clamping, over temperature protection by
current degeneration, VCC overvoltage protection and system output open/short
circuit protection.
Features:
Application:
• Constant current accuracy <±5%
