Overview
IS31LT3380
40V/1.
2A LED DRIVER WITH SWITCH DIMMING
OCTOBER 2011
GENERAL DESCRIPTION The IS31LT3380 is a continuous mode inductive step-down converter, designed for driving a single LED or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage.
The chip operates from an input voltage between 8.
5V and 40V and provides an output current up to 1.
2A.
The IS31LT3380 includes a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.
The IS31LT3380 includes an integrated output switch which has a very low conducting impedance to ensure high system efficiency.
The IS31LT3380 has switch dimming function...
