MAX16928CGUP/V+

Overview

The MAX16928CGUP/V+ is an automotive-grade TFT-LCD power supply integrated circuit designed for liquid crystal display applications. It integrates a boost converter and gate voltage regulator within a 20-pin TSSOP-EP package. The device operates with a supply voltage range of 3V to 5.5V and supports a switching frequency of 2.2MHz. It provides four non-isolated outputs, including 3.3V at 500mA, 12V at 400mA, 18V, and -5.9V. The component meets AEC-Q100 qualification standards and functions reliably across a temperature range of -40°C to 105°C.

Feature Summary

• Integrates boost converter and gate voltage regulator for LCD driving
• Automotive grade qualification ensuring reliability in vehicle environments
• Supports multiple output voltages for panel biasing and logic supplies

Applications

• Automotive TFT-LCD power systems
• In-vehicle infotainment display drivers
• Dashboard instrument cluster power management

Procurement Notes

Verify the specific suffix 'CGUP' against official Analog Devices documentation to confirm temperature rating and packaging details. Ensure compatibility with existing board layouts due to the 20-TSSOP-EP footprint. Cross-reference part numbers carefully as variations exist within the MAX16928 family. Confirm availability status directly with authorized distributors as supply conditions may vary.

Selection Notes

Select this component when designing power solutions for automotive displays requiring integrated boost and gate drive capabilities. Consider the 2.2MHz switching frequency for EMI management and filter size optimization. Evaluate thermal performance requirements given the operating temperature range and power dissipation characteristics of the TSSOP-EP package.

Part Context

This part belongs to the MAX16928 series of specialized PMICs for LCD applications. It is manufactured by Analog Devices Inc., formerly Maxim Integrated. The device is distinct from general-purpose regulators by its focus on multi-output generation for display panels. Related evaluation kits like the MAX16928EVKIT are available for design verification.

Replacement Considerations

Check for direct substitutes within the MAX16928 family such as MAX16928DGUP or MAX16928BGUP variants. Verify pinout and electrical parameter compatibility before substitution. Consult official cross-reference guides for any functional differences between suffixes.
