TS19705CX6 Taiwan Semiconductor Single Stage Flyback or Buck-Boost Current Control with Active PFC for LED lighting DESCRIPTION FEATURES TS19705 is constant current control IC with active ● Accuracy Constant Current <±3% power factor correction isolated or non-isolated AC-DC an isolated, primary-side-regulated Flyback controller ● ● ● Low BOM Cost Flyback or Buck-Boost w/o photocoupler Application Voltage Range: 90~264VAC or non-isolated Buck-Boost converter for LED lighting ● Built-in Active Power Factor Correction applications. The IC achieves high power factor and ● Good Line and Load Regulation low Total Harmonic Distortion (THD) operation by ● Open-LED Protection on DMG pin Boundary Conduction Mode (BCM). The line and load ● Over-Voltage Protection on VCC pin regulation of LED current is about <±3% because of ● Short-LED Protection particular control method. TS19705 also provides gate ● Cycle by Cycle Over Current Protection on CS pin driving voltage clamping, VCC overvoltage protection ● Over-Temperature Protection and system output open/short circuit protection to ● Gate Driving Voltage Clamping increase IC performance. APPLICATION LED lighting control. The TS19705 is configurable as SOT-26 ● LED lighting ● Down lights, Tube lamps, PAR Lamps, Bulbs Pin Definition: 1. COM 2. GND 3. CS 4. Output 5. VCC 6.
