MAX25520ATEB/V+

Power Management - Specialized Overview

The MAX25520ATEB/V+ is an automotive-grade, dual-output power IC designed for TFT-LCD applications. It integrates a current-mode boost converter and a current-mode inverter with an external rectifier to generate symmetrical or asymmetrical positive and negative voltages up to ±10.5V (±12V). The device operates from a supply voltage range of 2.65V to 5.5V and supports switching frequencies of 420kHz or 2.1MHz. It features a shutdown current of 10µA and functions within an operating temperature range of -40°C to +125°C.

Power Management - Specialized Procurement Notes

Verify the specific suffix (e.g., V+, VY+) against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets the required automotive grade standards for your target application environment. Cross-reference the ordering number with Analog Devices documentation to avoid substitution errors due to minor packaging variations.

Power Management - Specialized Selection Notes

Select this component when designing automotive TFT-LCD drivers requiring a compact, single-chip solution for generating dual polarity voltages. Consider the integrated nature of the boost and inverter stages to reduce external component count. Verify that the input supply voltage falls within the 2.65V to 5.5V range and that the thermal performance suits the -40°C to +125°C operating window.

Power Management - Specialized Part Context

This part belongs to Maxim Integrated's family of automotive LCD power management solutions. It is specifically engineered to replace discrete boost and inverter circuits in display driver boards. The device simplifies board layout by integrating control loops and protection features typically found in multi-component designs.

Power Management - Specialized Replacement Considerations

Consult the official Analog Devices replacement guide for direct pin-compatible alternatives. Verify that any substitute maintains the same automotive AEC-Q100 qualification status and output voltage capabilities.
