MAX16813ATP+T

LED Driver IC Overview

The MAX16813ATP+T is an integrated, four-channel high-brightness LED driver IC designed for automotive and general lighting applications. It features a wide input voltage range of 4.75V to 40V and supports direct connection to automotive load-dump events. The device integrates a current-mode switching DC-DC controller supporting boost, coupled-inductor boost-buck, or SEPIC topologies with an adjustable frequency range of 200kHz to 2MHz. Each channel provides up to 150mA of output current. It operates within a temperature range of -40°C to +125°C and is housed in a 20-TQFN package.

LED Driver IC Feature Summary
