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.
