L6713ATR

Special Purpose Regulators Overview

The L6713ATR is a switching controller designed for Intel VR10, VR11, and AMD CPU voltage regulation. It implements a two or three-phase step-down architecture with integrated high-current drivers. The device supports output voltages ranging from 0.3V to 1.6V. It features phase-shift configurations of 180 degrees for two phases and 120 degrees for three phases. The component operates at a maximum frequency of 225kHz and provides three independent outputs. It is housed in a 64-pin TQFP-EP package (10x10mm) suitable for surface mount applications.

Special Purpose Regulators Feature Summary

• Integrated high-current drivers eliminate the need for external gate drive components
• Supports flexible two or three-phase operation with precise phase shifting
• Compatible with Intel VR10, VR11, and AMD processor voltage requirements

Special Purpose Regulators Applications

• Intel VR10 compliant CPU voltage regulator modules
• Intel VR11 compliant CPU voltage regulator modules
• AMD processor voltage regulation systems

Special Purpose Regulators Procurement Notes

Verify the specific ordering suffix 'ATR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 64-TQFP-EP package dimensions align with the target PCB footprint. Ensure compatibility with the intended processor power management specifications before finalizing procurement orders.

Special Purpose Regulators Selection Notes

Select this component when designing multi-phase buck converters for modern processors requiring VR10 or VR11 compliance. The integrated driver capability simplifies bill of materials by reducing external component count. Consider the thermal performance of the exposed pad package for high-current applications.
