MAX8810AETM+T

Overview

The MAX8810AETM+T is a synchronous, 3-phase step-down current-mode controller with integrated dual MOSFET drivers. Designed for Intel VRD11/VRD10 and AMD K8 Rev F CPU core supplies, it supports flexible configurations for high-current applications up to 150A. The device features true-differential remote output-voltage sensing for precise regulation, eliminating trace impedance effects. It includes a tri-state SEL input for VID logic configuration, an enable input, and a power-good signal for startup sequencing. The SS/OVP pin allows soft-start programming and overvoltage indication.

Feature Summary

• Synchronous 3-phase step-down architecture with integrated dual MOSFET drivers
• True-differential remote output-voltage sensing for load-accurate regulation
• Tri-state SEL input for configurable VID logic compatibility
• Soft-stop feature prevents negative voltage spikes at turn-off

Applications

• Intel VRD11 compliant CPU core power supplies
• AMD K8 Rev F processor core power systems
• Low-voltage high-current CPU core power requirements

Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm package type and temperature range. Confirm RoHS compliance status via the manufacturer's datasheet. Check current availability as distribution channels may list limited stock or obsolete status. Ensure the ordering part number matches the specific electrical characteristics required for your design.

Selection Notes

Select this component when designing power stages for processors requiring VRD11 or AMD K8 Rev F compliance. The integrated drivers simplify board layout by reducing external component count. Verify that the target application requires a 3-phase topology and can utilize the differential sensing capability for optimal transient response and accuracy.

Part Context

This part belongs to the MAX8809A/MAX8810A family of synchronous controllers. These devices are engineered specifically for next-generation high-current CPUs. They offer flexible phase configurations and precision control loops to meet stringent voltage tolerance requirements of modern microprocessors.

Replacement Considerations

The MAX8809A is a compatible alternative within the same family, offering 2-phase or 4-phase flexibility alongside the 3-phase option.
