MAX17526AATP+T

Overview

The MAX17526AATP+T is a high-voltage DC-DC synchronous buck converter from the Himalaya uSLIC series. It operates with an input voltage range of 5.5V to 60V and delivers up to 6A of output current. The device features adjustable overvoltage protection (OVP) and overcurrent protection (OCP). It utilizes a fixed 200kHz switching frequency, which can be synchronized or adjusted between 200kHz and 2.2MHz. The component is housed in a 20-TQFN (5x5mm) package with an exposed pad for thermal management.

Feature Summary

• Integrated adjustable overvoltage protection circuitry
• Programmable overcurrent protection limits
• Synchronous rectification for high efficiency
• Wide input voltage capability

Applications

• Industrial power distribution systems
• Automotive electronics modules
• Telecommunications infrastructure equipment
• High-voltage battery-powered devices

Procurement Notes

Verify the specific suffix 'TP' confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the 'A' grade designation meets the required temperature and performance specifications for the target application environment. Ensure compatibility with the 20-WQFN footprint during PCB layout verification.

Selection Notes

Select this component when a robust solution for high-input voltage buck conversion is required. It is suitable for designs needing integrated fault protection without external sensing components. Consider the thermal requirements of the 6A output capability and ensure adequate copper area on the PCB for the exposed pad to maintain junction temperatures within safe operating limits under full load conditions.

Part Context

This part belongs to Maxim Integrated's Himalaya uSLIC family of power modules, designed for compact, high-density power solutions. These modules integrate the controller, power switches, and inductor into a single package to minimize board space. The MAX17526 specifically targets applications requiring wide input ranges and high reliability in harsh environments.

Replacement Considerations

Direct replacements include other Himalaya uSLIC variants such as the MAX17506 or MAX17532, depending on current and voltage requirements. Verify pinout compatibility and control interface similarities before substituting. Cross-reference datasheets for thermal resistance and protection threshold differences.
