MAX8621ZETG

Power Management - Specialized Overview

The MAX8621ZETG is a dual step-down PMIC designed for portable devices. It operates with an input supply voltage range of 2.6V to 5.5V and supports an operating temperature range of -40°C to +85°C. The device integrates two independent buck converters, each capable of delivering up to 500mA of output current. It utilizes a switching frequency of 4MHz to enable compact passive component selection. The component is housed in a 24-WFQFN exposed pad package (4x4mm) for surface mount mounting.

Power Management - Specialized Feature Summary

• Dual integrated step-down DC-DC converter architecture
• High-frequency 4MHz switching operation for size reduction
• Compact 24-pin QFN package with exposed thermal pad

Power Management - Specialized Applications

• Handheld mobile devices
• Portable consumer electronics
• Battery-powered equipment

Power Management - Specialized Procurement Notes

Verify the specific suffix (e.g., Z vs Y) against the official datasheet to confirm pinout and electrical characteristics. Confirm RoHS compliance status as variations exist within the product line. Check for end-of-life or limited availability status before finalizing design-in decisions.

Power Management - Specialized Selection Notes

Select this component when space-constrained designs require dual isolated power rails from a single battery source. The 4MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure the total load current does not exceed the 500mA per channel limit.

Power Management - Specialized Part Context

This part belongs to the Maxim Integrated MAX8621 series of specialized power management ICs. It is engineered specifically for applications requiring efficient power conversion in small form factors. The series typically includes variants with different packaging or thermal options.

Power Management - Specialized Replacement Considerations

Check for MAX8621YETG+ as a potential alternative variant. Verify that the replacement matches the 24-WFQFN package dimensions and thermal requirements. Confirm functional equivalence regarding the 500mA current rating and 4MHz switching frequency.
