LT3797 Product details

Description

Controller The LT®3797 is a triple output DC/DC controller designed to drive three strings of LEDs.The fixed frequency, current mode architecture results in stable operation over a wide range of supply and output voltages.The LT3797 includes an integrated DC/DC converter to produce a regulated 7.5V supply for the N-channel MOSFET gate drivers of the three channels.This high efficiency converter enables the part to operate from a wide input voltage range from 2.5V to 40V.The LT3797 is desig
