TS19320CS Phase-Cut Dimmable Flyback or Buck-Boost Current Control with Active PFC for LED lighting
■Description
●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, V-CC overvoltage protection and system output open/short circuit protection.
