MAX17511GTL+

Overview

The MAX17511GTL+ is a specialized power management IC designed for Intel IMVP-7 and VR12™ compliant CPU voltage regulation. It features a Quick-PWM™ controller architecture with two independent output channels housed in a 40-WFQFN (5x5 mm) package with an exposed pad. The device supports synchronous buck conversion, integrating high-side and low-side drivers to minimize external component count. It operates within standard industrial temperature ranges and provides precise voltage tracking and sequencing capabilities essential for modern processor power delivery systems.

• Mobile platform CPU power supply designs
• High-density server and workstation CPU power delivery
• Embedded system central processing unit voltage regulation

Procurement Notes

Verify the specific suffix 'GTL+' indicates RoHS compliance and lead-free status as per Analog Devices specifications. Confirm the package marking matches the 40-WFQFN configuration. Ensure the source document explicitly lists this part number as active or obsolete to determine availability constraints. Cross-reference the manufacturer's official ordering guide for any recent product change notifications affecting this specific variant.

Selection Notes

Select this component when designing for Intel IMVP-7 or VR12 architectures requiring dual-phase or multi-phase CPU power delivery. The integrated driver capability reduces bill-of-materials complexity compared to discrete controller solutions. Evaluate the thermal performance of the exposed pad design against the expected current load. Ensure the input voltage range and output voltage settings align with the target processor's power requirements.
