MAX8668ETET+T

Overview

The MAX8668ETET+T is a power management integrated circuit featuring two synchronous step-down DC-DC converters and two low-dropout linear regulators. It operates with a switching frequency of 1.5 MHz and provides four independent outputs. The buck converters deliver up to 1.2 A output current with adjustable voltages ranging from 600 mV to 3.3 V. The device functions within an ambient temperature range of -40°C to +85°C and is housed in a TQFN-16 package.

Feature Summary

• Integrates dual synchronous buck converters and dual LDOs for comprehensive power distribution
• Features individual enable controls for each regulator channel to optimize power efficiency
• Supports high-frequency operation at 1.5 MHz to minimize external component size

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Embedded systems utilizing mixed-signal power architectures
• Industrial control modules needing compact power solutions

Procurement Notes

Verify the exact suffix designation, as the provided model includes a trailing 'T' indicating tape-and-reel packaging, while official datasheets may list the base part without it. Confirm RoHS compliance status through manufacturer documentation. Check for end-of-life notifications or obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when a single IC solution is required to manage both switching and linear regulation needs. Ensure the design accommodates the specific thermal requirements of the TQFN-16 package. Verify that the input voltage range aligns with the system's power source capabilities before implementation.

Part Context

This component belongs to the MAX8668 family of power management ICs manufactured by Analog Devices under the Maxim Integrated brand. It serves as a consolidated power supply controller designed to reduce board space and simplify bill of materials for complex electronic systems requiring multiple voltage levels.

Replacement Considerations

Public records indicate the MAX8668ETET+ variant has reached end-of-life status. Designers should consult official substitution guides for compatible alternatives within the same product family or equivalent performance specifications.
