MAX16838ATP+T

LED Driver IC Overview

The MAX16838ATP+T is an integrated, two-channel high-brightness LED driver featuring a high-voltage boost and SEPIC controller. It operates with PWM dimming and supports multiple topologies including step-down (buck), step-up (boost), and SEPIC configurations. The device provides regulated current output up to 150mA per channel. It is housed in a 20-pin TQFN package with an exposed pad for thermal management.

LED Driver IC Feature Summary

• Integrated dual-channel architecture combining LED drivers with high-voltage power stage controllers
• Supports flexible topology selection including buck, boost, and SEPIC configurations for diverse LED string arrangements
• Enables precise brightness control through pulse-width modulation (PWM) dimming interface

LED Driver IC Applications

• Automotive exterior lighting systems requiring high-brightness LED regulation
• Industrial illumination fixtures utilizing multi-string LED arrays
• General solid-state lighting applications needing isolated or non-isolated drive solutions

LED Driver IC Procurement Notes

Verify the specific suffix 'ATP' against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad specifications. Ensure the component meets required automotive or industrial qualification standards if applicable to your design. Cross-reference the exact part number with Analog Devices documentation to avoid confusion with similar variants like MAX16838AUP.

LED Driver IC Selection Notes

Select this component when designing circuits that require independent control of two high-brightness LED channels from a single IC. It is suitable for applications where space constraints favor an integrated solution over discrete MOSFETs and controllers. Consider the input voltage range and required LED forward voltage drop to determine if buck, boost, or SEPIC topology is optimal for the specific load configuration.

LED Driver IC Part Context

This part belongs to the Maxim Integrated line of LED lighting drivers, now under Analog Devices. The MAX16838 series is designed for robust performance in demanding lighting environments. It integrates gate drivers and protection features typically found in separate components, simplifying the bill of materials and reducing board space requirements for complex LED driving architectures.
