NEW PRODUCT ANNOUNCEMENT www.taiwansemi.com TS19706CS Single-Stage Flyback or Buck-Boost Current Control with Active PFC and Integrated High Voltage MOSFET SOP-8 Pin Definition: 1. GND 2. COM 3. DMG 4. Vcc 8. CS 7. NC 6. DRAIN 5. DRAIN 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. The line and load regulation of LED current are easily maintained to <±3%. TS19706CS also provides over temperature protection, VCC overvoltage protection, and system output open and short circuit protection. Advantages: Application: • Supports isolated (Flyback) and non-isolated (Buck-boost) topology • Fits wide range of LED lighting application requirements • Excellent temperature compensation in both load / line regulation • Accurate constant current output <±3% in over wide temperature range • Boundary Conduction Mode (BCM) operation • Higher conversion efficiency and reduced EMI with fewer external components • Meeting EN55015_CE_Mains_ClassB • Competitive BOM design • Low Bill of Material design • Integrated 630V HV MOSFET • Internal active Power Factor Correction in Flyback topology • LED lamps <15W ISSUE NO.3 JUN 2016 NEW PRODUCT ANNOUNCEMENT www.taiwansemi.com Typical Application Circuit: NP Fuse L1 MOV VF NS NP Fuse RSN1 XC1 RSTR1 CBULK CSN1 LS LP DSN VO CO L1 MOV RSN1 XC1 RSTR1 CSN2 RSN2 RSTR2 DMG RD1 NA GND DA DRN CY RS LA CS CO VF CSN2 RSN2 RA DRN COM CCOM RD2 LP DSN TS19706CS RA VCC LA CSN1 RSTR2 TS19706CS DA CBULK RD1 RD2 DRN DMG DRN COM CCOM CA NA VCC GND RS CS CA Flyback Converter Buck-Boost Converter Key Performance: Part Number Input Voltage (V) Output Voltage (V) LED Current (mA) Efficiency (%) Operating Temperature Range (°C) PFC Topology TS19706CS 230 14 700 82.3 -40 ~ 105 Yes Flyback TS19706CS 230 100 147 91.96 -40 ~ 105 No Buck-Boost Ordering Information: Ordering Part Number Outline (Package) TS19706CS RLG SOP-8 Reel Reel Size Inner Box Carton Carton Size Gross Weight (pcs) (inch) (pcs) (pcs) (mm) (kg/ carton) 2,500 13 5,000 25,000 360*355*270 7.6 Samples of TS19706CS can be ordered on Product Detail page: http://www.taiwansemi.com/en/products/details/TS19706CS For pricing and more information, please contact TSC sales or authorized distributors worldwide: www.taiwansemi.com/en/contact ISSUE NO.3 JUN 2016 VO
