1 / 9 page  TS19706CS Taiwan Semiconductor 1 Version: A1605 Single-Stage Flyback or Buck-Boost Current Control with Active PFC and Integrated High Voltage MOSFET DESCRIPTION TS19706CS is a very efficient constant current controller IC for low cost non-dimmable LED lighting applications. The TS19706CS is configurable for either isolated primary side Flyback regulation or non- isolated buck-boost current regulation topology. Integrated 630V Power MOSFET and active power factor correction in Flyback mode reduces the external components required and BOM for implementation. The IC achieves high power factor correction and low total harmonic distortion (THD) with Boundary Conduction Mode (BCM) operation. Temperature compensation of line/load regulation allows constant current accuracy to be maintained to <±3%. TS19706CS also provides over temperature protection, VCC overvoltage protection, and system output open and short circuit protection. FEATURES ● Integrated 630V MOSFET ● Constant Current Accuracy within <±3% ● Primary-Side Feedback Control ● Application Voltage Range 80 VAC ~ 308 VAC ● Transition-Mode PFC Operation ● Built-in Active Power Factor Correction ● Good Line and Load Regulation ● Open-LED Protection on DMG pin ● Over-Voltage Protection on VCC pin ● Short-LED Protection ● Cycle-by-Cycle Over Current Protection on CS pin ● Over-Temperature Protection ● Compliant to RoHS Directive 2011/65/EU and WEEE 2002/96/EC. ● Halogen-free according to IEC 61249-2-21. APPLICATION ● LED lighting ● Down lights, Tube lamps, PAR Lamps, Bulbs SOP-8 Pin Definition: 1. GND 8. CS 2. COM 7. NC 3. DMG 6. DRN 4. VCC 5. DRN Notes: MSL 3 (Moisture Sensitivity Level) per J-STD-020 TYPICAL APPLICATION CIRCUIT Flyback Converter Buck-Boost Converter |
