MAX16928CGUP/V+T

Overview

The MAX16928CGUP/V+T is an automotive-grade LCD driver and TFT-LCD power supply designed for high-efficiency operation. It integrates a boost converter, a 3.3V regulator controller, and a buck converter within a single package. The device operates with a supply voltage range of 3V to 5.5V and draws a typical supply current of 750mA. It is housed in a 20-TSSOP-EP (Exposed Pad) package, suitable for surface-mount installation. The component meets AEC-Q100 qualification standards for automotive applications.

Feature Summary

• Integrates multiple power conversion stages including boost, buck, and linear regulation functions into a single compact solution.
• Optimized specifically for driving automotive TFT-LCD displays with dedicated control features.
• Complies with AEC-Q100 automotive reliability standards for harsh operating environments.

Applications

• Automotive TFT-LCD display power systems
• In-car infotainment screen drivers
• Digital instrument cluster power management

Procurement Notes

Verify the specific suffix 'CGUP/V+T' against official Analog Devices documentation to confirm pinout and thermal pad configuration. Ensure compatibility with existing PCB footprints for the 20-TSSOP-EP package. Confirm that the automotive grade qualification aligns with your system's environmental requirements before finalizing procurement.

Selection Notes

Select this component when designing power supplies for automotive TFT-LCD panels requiring integrated boost and buck regulation. It is suitable for applications needing a compact solution that reduces external component count. Consider the 3V to 5.5V input range and the specific thermal dissipation capabilities of the exposed pad TSSOP package during layout design.

Part Context

This part belongs to the MAX16928 series of highly integrated power management ICs from Maxim Integrated, now part of Analog Devices. These devices are engineered to simplify the design of complex display power architectures by combining multiple regulators into one chip, thereby saving board space and reducing overall system complexity in automotive electronics.

Replacement Considerations

Check for direct cross-references within the MAX16928 family, such as the MAX16928BGUP/V+T or MAX16928AGUP/V+T, which may share identical electrical characteristics but differ in temperature grades or packaging variants. Verify functional equivalence before substitution.
