LED Driver IC datasheet and documents for LT3492IFE#TRPBF

LT3492IFE#TRPBF

LED Driver IC Overview

The LT3492IFE#TRPBF is a triple output DC/DC converter designed as a constant-current source for driving LEDs. It operates in buck, boost, or buck-boost modes with an input voltage range of 3V to 30V. Each channel features internal switches rated at 600mA and 60V. The device supports adjustable switching frequencies between 330kHz and 2.1MHz. It provides up to 3000:1 PWM dimming ratio via an external input. Output current is set by an external sense resistor ranging from 10mV to 100mV. The CTRL pin allows for analog dimming or overtemperature protection. It is housed in a 28-TSSOP-EP package.
