MAX8667ETEJS+T

Overview

The MAX8667ETEJS+T is a quad-output power management IC featuring two synchronous buck converters and two low-dropout linear regulators. It operates within an input voltage range of 2.8 V to 5.5 V. The device integrates high-frequency switching at 1.5 MHz for efficient power conversion. Output configurations include specific voltage and current ratings, such as 1.2 V at 600 mA and 1.8 V at 1.2 A. It is housed in a 16-TQFN package with an exposed pad, designed for surface-mount installation.

Feature Summary

• Integrates dual synchronous buck converters and dual LDOs for comprehensive power distribution
• Supports high-frequency operation at 1.5 MHz to minimize external component size
• Provides flexible output voltage regulation across multiple rails

Applications

• Portable medical devices requiring multi-rail power supplies
• Battery-powered instrumentation systems
• Embedded consumer electronics with space constraints

Procurement Notes

Verify the exact suffix against official documentation, as ordering codes may indicate specific packaging or revision differences. Confirm availability status directly with authorized distributors, as supply conditions change frequently. Ensure the component meets required environmental standards and RoHS compliance before integration into final designs.

Selection Notes

Select this component when a compact solution for four distinct power rails is necessary. Evaluate thermal performance requirements given the TQFN package and exposed pad design. Compare efficiency characteristics against discrete solutions to determine suitability for battery-operated applications where power conservation is critical.

Part Context

This part belongs to the MAX8667 series, which focuses on integrated power management for portable applications. The series typically combines switching and linear regulation technologies to optimize board space and system efficiency. It serves as a specialized PMIC for designs requiring multiple regulated outputs from a single source.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Verify that substitute components match the required output voltages and current capabilities. Ensure interface compatibility and thermal characteristics align with existing board layouts.
