MAX8667ETEAC+T

Overview

The MAX8667ETEAC+T is a quad-output power management IC featuring two synchronous buck converters and two low-dropout regulators. It operates from an input voltage range of 2.8V to 5.5V with a switching frequency of 1.5MHz. The device provides four independent outputs: Output 1 delivers 1.2V at 600mA, Output 2 supplies 1.8V at 1.2A, Output 3 offers 2.8V at 300mA, and Output 4 provides a fixed 3.3V. Designed for mobile applications, it utilizes a 16-TQFN package.

Feature Summary

• Integrates dual synchronous step-down DC-DC converters and dual LDOs in a single compact package
• Provides individual enable controls for each output regulator to optimize system power consumption
• Supports flexible output configurations through adjustable or fixed voltage options across four channels

Applications

• Powering low-voltage FPGA cores and I/O banks requiring specific voltage levels
• Supplying DDR3 memory modules with stable 1.8V rails
• Mobile handheld devices requiring efficient multi-rail power distribution

Procurement Notes

Verify the exact suffix 'AC' against official Analog Devices documentation to confirm pin compatibility and thermal pad specifications. Confirm current lifecycle status as this component family may have discontinuation notices. Ensure the ordering part number matches the required tape-and-reel quantity if applicable.

Selection Notes

Select this component when a compact solution is needed for multiple voltage rails in space-constrained designs. Evaluate the 1.2A capability of the second buck converter against peak load requirements. Consider the 1.5MHz switching frequency for trade-offs between inductor size and electromagnetic interference.

Part Context

This part belongs to the MAX8667 series of highly integrated PMICs designed for portable electronics. It consolidates multiple discrete regulators into one chip to reduce board area. The ETEAC suffix indicates specific factory binning or packaging variations within the standard TQFN-16 form factor.
