MAX16814BUUP+T

LED Driver IC Overview

The MAX16814BUUP+T is a high-efficiency, four-channel high-brightness LED driver IC from Analog Devices/Maxim Integrated. It integrates a current-mode switching DC-DC controller with four linear LED current-sink channels. The device supports an input voltage range of 4.75V to 40V and withstands automotive load-dump events. Each channel provides adjustable LED current from 20mA to 150mA with ±3% accuracy. The integrated DC-DC controller operates at a programmable frequency between 200kHz and 2MHz, supporting boost, SEPIC, and coupled-inductor topologies. It is housed in a 20-pin TSSOP-EP package.
