800mA Buck (Step-down) WLED Driver SOT-25 Pin Definition: 1. VIN 2. Ground 3. CT 4. ISENSE 5. SW www.DataSheet4U.com TS19373 General Description The TS19373 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The device operates from an input supply between 6V and 40V and provides an externally adjustable output current of up to 800mA. TS19373 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.
