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.

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

Application

● LED Flashlights

● White LED Backlighting

● White LED Driving

● Multiple LED Driving

● LED Lighting Equipment
