COM Power supply Voltage sense Current sense Op amp out for photocoupler No connection Comp out for current cut off PWM pulse filter The TS19340CS14 provides an integrated solution using built in switch mode constant current (CC) and constant voltage (CV) regulation smart LED lighting applications. The built in PWM and linear dimming functions allows the designer to replace many external discrete components used for dimming schemes. The PWM frequency is configurable from 100Hz-10kHz through selection of the compensation capacitor. The linear dimming cut off voltage is configurable using a resistor divider at the CCO pin. Advantages: • High level of integration, low BOM cost • Ideally suited for use on small PCBs with high component densities. • Single device solution includes constant current (CC) and constant voltage (CV) regulation • Supports wide range of supply power from primary side • The wide supply voltage of 7.6V to 35V ensures compatibility with common LED lighting applications including luminaries, troffers, downlights, sconces, office lighting and signage • Adjustable DIM-to-off • Integrated Current Cut Off level set with resistor divider 200mV 200mV High Current Limit, ADJ By CCH 0 Low Current Limit, ADJ By CCL Low Current Limit, ADJ By CCL Cut- Off Current, ADJ By CCO Cut- Off Current, ADJ By CCO 100 PWM (%) LED Current Ratio vs. PWM Duty Ratio ISSUE NO.4 JUN 2016 0 3.2 CCH(V) LED Current Ratio vs. Linear Dimming Voltage NEW PRODUCT ANNOUNCEMENT www.taiwansemi.com Typical Application Circuit: Secondary Side Primary Side Secondary Side Primary Side Photo coupler Photo coupler for special function for special function Photo coupler Photo coupler VCC FB VSEN PHO SWO COM VD CCH CCL CCO PWM GND 3.3VD VCC FB VSEN PHO SWO COM VD CCH CCL CCO PWM GND 3.3VD 2R PWM Duty 100%~0% PWM Dimming Application Circuit Outline (Package) SOP-14 R Analog input 10V~0V 3.3VD Linear Dimming Application Circuit Reel Reel Size Inner Box Carton Carton Size (pcs) (inch) (pcs) (pcs) (mm) 2,500 13 5,000 25,000 360*355*270 Gross Weight Packing Code (kg/ carton) 7.9 RLG Samples of TS19340CS14 can be ordered on Product Detail page: http://www.taiwansemi.com/en/products/details/TS19340CS14 For pricing and more information, please contact TSC sales or authorized distributors worldwide: www.taiwansemi.com/en/contact ISSUE NO.4 JUN 2016
