MAX20069CGTL/V+

Overview

The MAX20069CGTL/V+ is an automotive-grade, I²C-controlled power supply and LED backlight driver IC designed for TFT-LCD applications. It integrates four independent boost converters capable of driving up to four LED strings with phase shifting to minimize EMI. The device supports input voltages from 4.5V to 5.5V or 4.5V to 42V depending on configuration, with output voltages adjustable up to 18V per channel. It operates within a temperature range of -40°C to 150°C and utilizes a 40-WFQFN exposed pad package.

Feature Summary

• Integrates four high-current boost converters for simultaneous TFT-LCD power and LED backlight drive
• Features I²C control interface for precise regulation and system management
• Includes phase-shifting capability across channels to reduce electromagnetic interference
• Automotive qualification ensures reliability in harsh operating environments

Applications

• Automotive TFT-LCD display power systems
• Multi-string LED backlight drivers for vehicle infotainment screens
• I²C-controlled power management modules for automotive displays

Procurement Notes

Verify the exact suffix (GTL/V+) against the manufacturer's current datasheet to confirm pinout and electrical specifications. Confirm automotive grade qualification status and lead times directly with authorized distributors, as availability may vary by region. Ensure the selected package matches the PCB footprint requirements.

Selection Notes

Select this component when designing automotive display systems requiring integrated power and backlight control. It is suitable for applications needing four independent LED channels with EMI reduction features. Consider the input voltage range compatibility with the vehicle's power bus and the thermal performance of the 40-WFQFN package under maximum load conditions.

Part Context

This part belongs to Maxim Integrated's family of automotive display drivers. It combines power conversion and LED driving functions into a single solution, reducing board space and component count compared to discrete designs. The integration simplifies the design of complex automotive LCD backlights while maintaining high efficiency and reliability standards required for automotive electronics.

Replacement Considerations

Check for direct pin-to-pin replacements within the same product family that may offer updated revisions or different thermal packages. Verify functional equivalence regarding I²C commands and electrical parameters before substitution.
