LT3492EUFD#PBF

LED Driver IC Overview

The LT3492EUFD#PBF is a triple output DC/DC converter designed as a constant-current source for driving high current LEDs. It operates in buck, boost, or buck-boost modes using a fixed frequency current mode architecture. The device features three independent driver channels with built-in gate drivers for external PMOS LED disconnects. Each channel supports up to 600mA output current and includes internal 60V switches. A frequency adjust pin allows programming between 330kHz and 2.1MHz. The input voltage range spans from 3V to 30V.
