MAX16929GGUI/V+

Overview

The MAX16929GGUI/V+ is an automotive-grade LCD driver and power supply integrated circuit designed for TFT-LCD applications. It integrates a step-down DC-DC converter, five LDO regulators, and an LCD bias generator. The device operates from a 28V input supply and features a 2MHz switching frequency. It is housed in a 28-pin TSSOP-EP package and meets AEC-Q100 qualification standards for automotive reliability.

Feature Summary

• Integrates a high-efficiency buck converter with multiple low-dropout linear regulators for comprehensive power management
• Includes a dedicated LCD bias generator to support panel driving requirements
• Qualified for automotive environments ensuring robust performance under varying thermal conditions

Applications

• Automotive TFT-LCD power supply systems
• In-vehicle display driver circuits
• Dashboard and infotainment screen power management

Procurement Notes

Verify the specific suffix GGUI/V+ against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with AEC-Q100 automotive standards if required for your application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest datasheet revision.

Selection Notes

Select this component when designing automotive displays requiring a single-chip solution for both logic power and LCD bias generation. The integrated buck converter reduces external component count compared to discrete designs. Consider the 28-pin TSSOP-EP package for thermal dissipation needs. Verify that the 28V input range matches the vehicle's electrical system specifications.

Part Context

This part belongs to the MAX16929 family of automotive LCD drivers. It combines power management and display driving functions into a single IC. The series is optimized for reducing board space and simplifying design in automotive infotainment and instrument cluster applications. It replaces older multi-component solutions by integrating buck, LDO, and bias stages.

Replacement Considerations

Check for MAX16929AGUI/V+T as a potential variant within the same family. Verify pinout and electrical specifications before substitution. No direct cross-manufacturer replacements are confirmed in public data.
