1 / 6 page TS19372 Buck (Step-down) WLED Driver with External Switch 1/6 Version: A09 SOT-25 General Description The TS19372 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 300mA output current to drive external N-channel MOSFET. TS19372 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current. Application ● LED Flashlights ● White LED Backlighting ● White LED Driving ● Multiple LED Driving ● LED Lighting Equipment Features ● Wide Input Voltage Range 6V~40V ● 300mA Output Current ● High Efficiency up to 92% ● Drives up to 3 (1~3W) LEDs @ VIN 12V ● Drives up to 7 (1~3W) LEDs @ VIN 24V ● 180kHz Switching Frequency ● Internal PWM Filter Ordering Information Part No. Package Packing TS19372CX5 RF SOT-25 3Kpcs / 7” Reel Block Diagram Pin Definition: 1.
