MAX8524EEI

Overview

The MAX8524EEI+T is a switching controller designed for Voltage Regulator Modules (VRM) supporting 2 to 8 phases. It integrates a 9.1 PWM controller with a Buck topology. The device operates within a switch frequency range of 150 kHz to 1.2 MHz and provides four outputs. It supports an output voltage of 1.1 V and an output current of 84 mA. The component functions between -40°C and +85°C, housed in a QSOP-28 package.

Feature Summary

• Supports multi-phase VRM configurations from 2 to 8 phases
• Integrates a 9.1 PWM controller for precise regulation
• Features fast rise and fall times of 10 ns

Applications

• Voltage Regulator Module (VRM) designs
• Multi-phase power supply systems
• High-performance computing power management

Procurement Notes

Verify the specific suffix 'E' and '+T' against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Confirm end-of-life status as distributor records indicate discontinuation. Ensure compatibility with existing PCB footprints for the QSOP-28 housing before procurement.

Selection Notes

Select this component when designing multi-phase VRMs requiring integrated PWM control. Evaluate the 150 kHz to 1.2 MHz frequency range against thermal and efficiency requirements. Consider the 84 mA output current capability relative to load demands. Verify that the QSOP-28 package fits the assembly constraints.
