TS19340CS14 Taiwan Semiconductor

TS19340CS14 Taiwan Semiconductor Secondary-Side Constant Current and Constant Voltage Controller with PWM / Linear Dimming DESCRIPTION FEATURES Secondary-side CC and CV Control The TS19340CS14 provides an integrated solution High accuracy internal voltage reference using built in switch mode constant current (CC) and Build in PWM & Linear dimming functions constant voltage (CV) regulation for isolation smart LED current cut-off function LED lighting applications. The built in PWM and Built-in 3.3V reference for dimming Power linear dimming functions allows the designer to Compliant to RoHS Directive 2011/65/EU and in replace many external discrete components used for Accordance to WEEE 2002/96/EC. dimming schemes. The PWM frequency is Halogen-free according to IEC 61249-2-21 configurable from 100Hz-10kHz through selection of the compensation capacitor. The linear dimming cut APPLICATION off voltage is configurable using a resistor divider at LED lighting Intelligent lighting management the CCO pin SOP-14 Pin Definition: 1. V 14. V D CC 2. CCH 13.
