MAX16826ATJ+C24

LED Driver IC Overview

The MAX16826ATJ+C24 is a programmable, four-string high-brightness LED driver IC designed for automotive applications. It operates as a DC-DC controller utilizing SEPIC or boost topology to drive multiple LED strings from a single power source. The device supports PWM dimming and functions within a switching frequency range of 100kHz to 1MHz. It requires a supply voltage between 4.75V and 24V. The component is housed in a 32-TQFN (5x5) package with an exposed pad, rated for operation at temperatures from -40°C to 125°C.

LED Driver IC Feature Summary

• Supports four independent LED string outputs for uniform current distribution
• Integrates SEPIC and boost converter topologies for flexible input voltage handling
• Enables precise brightness control through PWM dimming interface
• Complies with automotive-grade reliability standards for harsh environments

LED Driver IC Applications

• Automotive exterior lighting systems
• High-intensity discharge lamp ballast drivers
• LED headlamp modules requiring multi-string configuration
• Industrial lighting fixtures with wide input voltage ranges

LED Driver IC Procurement Notes

Verify the specific suffix C24 against the official Analog Devices datasheet to confirm pinout and thermal pad specifications. Ensure the procurement channel provides valid RoHS compliance documentation. Check for obsolescence status as some distributors list this variant as discontinued. Confirm that the 32-TQFN footprint matches your PCB design constraints before ordering.

LED Driver IC Selection Notes

Select this component when designing circuits requiring independent control of four LED strings from a single input rail. It is suitable for applications where input voltage may drop below output requirements, necessitating SEPIC functionality. Consider the 32-TQFN package size for space-constrained automotive boards. Validate thermal performance at the upper limit of the 125°C operating range.

LED Driver IC Part Context

This part belongs to the MAX16826 family of LED drivers from Maxim Integrated, now part of Analog Devices. The family focuses on high-efficiency, multi-channel LED control for automotive and industrial markets. The ATJ+ designation indicates the standard automotive-grade temperature range and lead-free composition. Variants like the C24 suffix typically denote specific tape-and-reel packaging or regional certification requirements.
