MAX16928BGUP/V+T

Overview

The MAX16928BGUP/V+T is an automotive-grade TFT-LCD power supply integrating a boost converter and gate voltage regulator. It operates on a 3V to 5.5V supply with a 1.5mA supply current. The device provides a 5V to 15V output voltage range and features a 10µA shutdown current rating. It supports regulated outputs including 1.8V and 3.3V regulators. The component functions within a temperature range of -40°C to +105°C and is housed in a 20-TSSOP-EP package.

Feature Summary

• Integrates a boost converter and gate voltage regulator for automotive TFT-LCD applications
• Includes internal 1.8V and 3.3V linear regulators
• Certified to AEC-Q100 standards for automotive reliability

Applications

• Automotive TFT-LCD power supplies
• Boost converter circuits for display drivers
• Gate voltage regulation for LCD panels

Procurement Notes

Verify the specific suffix 'V+' indicates the qualified automotive grade variant when sourcing. Confirm the 20-TSSOP-EP package type matches your PCB footprint requirements. Ensure the supplier provides valid traceability documentation for AEC-Q100 compliance. Check for RoHS3 certification status prior to final procurement approval.

Selection Notes

Select this component for designs requiring a single-chip solution for automotive display power. The integrated boost and regulator structure reduces external component count. Verify input voltage compatibility with the 3V to 5.5V operating range. Ensure thermal management supports the specified -40°C to +105°C junction temperature limits.

Part Context

This part belongs to the MAX16928 series from Analog Devices/Maxim Integrated, designed specifically for automotive display systems. It replaces discrete boost and regulator solutions by combining them into one highly integrated PMIC. The series focuses on simplifying the power architecture for TFT-LCD modules in vehicles.

Replacement Considerations

Check for MAX16928AGUP/V+T as a potential alternative within the same family. Verify pinout and electrical specifications match before substitution. Ensure any replacement maintains AEC-Q100 qualification for automotive use.
