IS31LT3361
INTEGRATED NMOS SWITCH 40V/1.3A LED DRIVER WITH FAULT PROTECTION
May 2021
GENERAL DESCRIPTION
The IS31LT3361 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 supply between 6V and 40V and provides an externally adjustable output current of up to 1.3A.
The IS31LT3361 includes an integrated low-side output NMOS switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.
Output current can be adjusted linearly by applying an external control signal to the ADJ pin. The ADJ pin will accept either a DC voltage or a PWM waveform.
