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.

Features

● Wide Input Voltage Range 6V~40V

● 800mA Output Current

● High Efficiency up to 90%

● Drives up to 3 (1~3W) LEDs @ VIN 12V

● Drives up to 7 (1~3W) LEDs @ VIN 24V

● 180kHz Switching Frequency

● Internal PWM Filter

Application

● DC/DC or AC/DC LED driver applications

● Back lighting of flat panel displays

● Signage and decorative LED lightings

● Chargers

● LED Lighting Equipment – MR16, Tube
