MAX16929IGUI/V+T

Overview

The MAX16929IGUI/V+T is an automotive-grade LCD driver and power supply controller designed for TFT-LCD applications. It integrates a boost converter, two step-down converters, and an LCD bias generator within a single package. The device operates from an input voltage range of 3.5V to 36V and supports switching frequencies up to 2MHz. It is housed in a 28-pin TSSOP-EP package and meets AEC-Q100 qualification standards for automotive reliability.

Feature Summary

• Integrates multiple power stages including boost, buck, and bias generation for complete TFT-LCD power management
• Automotive qualified with AEC-Q100 certification for high reliability in vehicle environments
• Supports high-frequency operation up to 2MHz to minimize external component size

Applications

• Automotive TFT-LCD display power supplies
• In-vehicle infotainment system displays
• Digital instrument cluster power management

Procurement Notes

Verify the specific suffix 'IGUI/V+T' against official Analog Devices documentation to confirm temperature grade and tape-and-reel packaging configuration. Ensure compatibility with existing PCB footprints for the 28-TSSOP-EP package. Confirm current availability status as distribution channels may report limited stock or end-of-life conditions.

Selection Notes

Select this component when designing automotive displays requiring integrated power regulation for TFT panels. It is suitable for systems needing a compact solution that combines boost, buck, and bias functions. Consider thermal performance requirements due to the TSSOP-EP package and verify input voltage ranges match the vehicle's electrical architecture.

Part Context

This part belongs to the MAX16929 family of automotive LCD drivers. It shares functional similarities with other Maxim Integrated PMICs but is distinct in its specific integration of boost, buck, and bias generators tailored for TFT-LCD applications. The series is designed to replace discrete power solutions in automotive display modules.

Replacement Considerations

Check for direct substitutes such as MAX16929DGUI/V+T or MAX16929EGUI/V+T which share the same core functionality but may differ in temperature grades or packaging variants. Verify pinout compatibility before substitution.
