Overview

FEATURES n n n n n n n n LT3492 Triple Output LED Driver with 3000:1 PWM Dimming DESCRIPTION The LT®3492 is a triple output DC/DC converter designed to operate as a constant-current source and is ideal for driving LEDs.
The LT3492 works in buck, boost or buckboost mode.
The LT3492 uses a ﬁxed frequency, current mode architecture resulting in stable operation over a wide range of supply and output voltages.
A frequency adjust pin allows the user to program switching frequency between 330kHz and 2.
1MHz to optimize efﬁciency and external component size.
The external PWM input provides 3000:1 LED dimming on each channel.
Each of the three channels has a built-in gate driver to drive an external...
