LM3407MY/NOPB - TI Function Overview

The LM3407 device is a constant current output floating buck switching converter designed to provide constant current to high-power LEDs. The device is ideal for automotive, industrial, and general lighting applications. The LM3407 has an integrated power N-channel MOSFET that makes the application solution compact and simple to implement. An external 1% thick-film resistor allows the converter output voltage to adjust as needed to deliver constant current within 10% accuracy to a serially connected LED string of varying number and type. Converter switching frequency is adjustable from 300 kHz to 1 MHz. The LM3407 features a dimming input to enable LED brightness control by Pulse Width Modulation (PWM). Additionally, a separate enable pin allows for low-power shutdown. An exposed pad MSOP-8 package provides excellent heat dissipation and thermal performance. Input UVLO and output open-circuit protection ensure a robust LED driver solution.
