MAX25520ATEB/VY+T

Power Management - Specialized Overview

The MAX25520ATEB/VY+T is an automotive-grade, two-channel TFT-LCD power supply controller designed for display applications. It operates with a supply voltage range of 2.65 V to 5.5 V and delivers output voltages from 5 V to 15 V. The device features a low shutdown current of 10 µA and supports operation across a temperature range of -40°C to +105°C. Packaged in a 16-pin TQFN-EP (3x3 mm) format, it integrates synchronous rectification for efficient power conversion in infotainment systems.

Power Management - Specialized Procurement Notes

Verify the specific suffix 'VY+T' indicates tape-and-reel packaging when ordering. Confirm that the component meets AEC-Q100 standards if required for your specific automotive tier. Cross-reference the manufacturer part number with official Analog Devices documentation to ensure compatibility with your design-in requirements and regional availability constraints.

Power Management - Specialized Selection Notes

Select this component for designs requiring dual isolated outputs for LCD bias and backlight generation. Ensure the input voltage aligns with the 2.65 V to 5.5 V operating range. Consider the thermal performance of the exposed pad TQFN package for high-power dissipation scenarios. Validate that the 10 µA shutdown current meets the system's standby power specifications.

Power Management - Specialized Part Context

This part belongs to Maxim Integrated's family of automotive display power solutions. It complements other LCD driver ICs by providing the necessary high-voltage rails for panel operation. The series focuses on integrating multiple power functions into compact packages to reduce board space in modern vehicle interiors.

Power Management - Specialized Replacement Considerations

Check for direct pin-compatible alternatives within the MAX255xx series. Verify if older revisions or non-tape versions (e.g., MAX25520ATEB/VY+) meet the packaging needs. Consult Analog Devices for updated lifecycle status before substituting.
