Overview
The MAX8667ETEAA+ is a quad-output power management IC featuring two synchronous buck converters and two low-dropout linear 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 outputs: Output 1 delivers 600mA at 1.2V, Output 2 supplies 1.2A at 1.8V, Output 3 offers 300mA at 2.8V, and Output 4 is a fixed LDO. It is housed in a compact 16-TQFN (3x3) package with an exposed pad for thermal dissipation.
Feature Summary
- Integrates dual synchronous step-down DC/DC converters and dual low-dropout linear regulators within a single component.
- Supports flexible power rail generation through configurable buck outputs and dedicated LDO stages.
- Operates reliably across industrial temperature ranges from -40°C to +85°C.
Applications
- Pulse oximeter designs requiring multiple precise voltage rails
- Portable medical diagnostic equipment
- Battery-powered sensor systems
Procurement Notes
Verify current availability status as the component may be obsolete or discontinued. Confirm exact suffix specifications against official datasheets to ensure compatibility with existing designs. Check for valid RoHS compliance documentation before integration into regulated products.
Selection Notes
Select this part when space-constrained applications require combined switching and linear regulation capabilities. Ensure input voltage remains within the 2.8V to 5.5V operational window. Verify that the total output current requirements do not exceed individual channel limits specified in the electrical characteristics table.
Part Context
This component belongs to the MAX8667 family of PMICs designed for portable health monitoring devices. It consolidates power management functions typically requiring multiple discrete components, thereby reducing board area and simplifying schematic design for battery-operated medical instrumentation.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult manufacturer obsolescence notices for potential alternative recommendations.
