MAX8760ETL+

Overview

The MAX8760ETL+ is a dual-phase, Quick-PWM step-down controller designed for 6-bit VID AMD Mobile Turion 64 CPU core supplies. It operates within a specific input voltage range and provides two output channels. The device utilizes a TQFN-40 package with an exposed pad for thermal management. Key electrical characteristics include a switching frequency range of 200 kHz to 600 kHz, an output voltage range of 0 V to 1.5 V, and a maximum output current capability of 2.2 A per phase. The controller features fast rise and fall times of 20 ns and draws a supply current of 5 mA.

Feature Summary

• Implements Quick-PWM control architecture for high-efficiency power conversion
• Supports 6-bit VID interface for dynamic voltage adjustment
• Integrates dual-phase topology for reduced input ripple and improved transient response

Applications

• AMD Mobile Turion 64 CPU core voltage regulation
• Dual-phase step-down power supplies for mobile processors
• Low-voltage high-current DC-DC conversion systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance and lead-free soldering specifications against project requirements. Ensure the TQFN-40 package variant matches PCB footprint designs. Review official discontinuance notifications for availability constraints and recommended replacement strategies.

Selection Notes

Select this component for applications requiring precise voltage regulation for AMD Turion 64 platforms. Evaluate thermal performance given the TQFN-40 package constraints. Consider the 200 kHz to 600 kHz switching frequency range for inductor selection and EMI filtering. Verify compatibility with 6-bit VID signaling protocols used by the target processor.

Part Context

The MAX8760 belongs to Maxim Integrated's portfolio of specialized power management ICs targeting mobile computing applications. It is part of the Quick-PWM family, which emphasizes efficiency and compact design for portable devices. This series supports various CPU voltage regulator modules (VRMs) requiring fast transient response and low quiescent current.

Replacement Considerations

Consult official Analog Devices documentation for confirmed substitute part numbers. Check for pin-compatible alternatives within the same product family that maintain Quick-PWM functionality and AMD Turion 64 compatibility.
