MAX8660BETL+

Overview

The MAX8660BETL+ is a specialized Power Management IC (PMIC) from Analog Devices, designed for mobile applications. It integrates eight output regulators: four synchronous step-down (buck) converters and four low-dropout (LDO) linear regulators. The device operates with a switching frequency of 2 MHz and is housed in a 40-pin TQFN package.

Feature Summary

• Integrates four synchronous buck converters and four LDOs in a single compact package
• Features dynamic voltage management capabilities optimized for mobile power efficiency
• Supports high-frequency operation at 2 MHz to minimize external component size

Applications

• Mobile handheld devices requiring multi-rail power distribution
• Portable electronics utilizing single-cell lithium-ion battery systems
• Embedded systems needing combined switching and linear regulation

Procurement Notes

Verify the specific suffix 'B' against official datasheets to confirm pinout and electrical characteristics, as variations exist within the MAX8660 family. Confirm RoHS compliance status through current manufacturer documentation. Check for End-of-Life (EOL) notifications or discontinuance notices prior to final design approval to ensure long-term supply stability.

Selection Notes

Select this component when a system requires multiple regulated rails from a single source without excessive board space consumption. It is suitable for designs prioritizing high integration over discrete regulator solutions. Ensure input voltage ranges align with the battery profile and that thermal dissipation in the TQFN-40 package meets the application's power budget requirements.

Part Context

This part belongs to the MAX8660A/B series of PMICs developed by Maxim Integrated, now part of Analog Devices. These chips are engineered specifically for the stringent power and size constraints of modern mobile consumer electronics, offering a consolidated solution for complex power tree architectures.

Replacement Considerations

The MAX8660AETL+ is a related variant within the same product family. Verify functional compatibility and pinout equivalence before substitution, as differences may exist between the 'A' and 'B' suffixes regarding specific regulator configurations or performance parameters.
