MAX1820ZEBC

Overview

The MAX1820ZEBC is a high-performance linear voltage regulator and WCDMA 600mA buck converter designed for modern applications. It operates with an input voltage range of 2.6V to 5.5V and provides an adjustable output voltage from 400mV to 3.4V. The device delivers up to 600mA of output current in a compact 10-WFBGA package. It supports single +5V or dual ±5V supplies, ensuring efficient power management for DDR and other critical loads.

Feature Summary

• Integrated 600mA buck converter topology for efficient power conversion
• Adjustable output voltage range suitable for various digital loads
• Compact surface-mount packaging for space-constrained designs

Applications

• DDR memory power supply
• WCDMA base station components
• General-purpose DC-DC conversion

Procurement Notes

Verify the specific suffix (e.g., +T) for tape-and-reel availability. Confirm RoHS compliance status as some variants may differ. Check lead times due to potential limited supply situations. Ensure the 10-WFBGA footprint matches your PCB layout requirements before ordering.

Selection Notes

Select this component when a 600mA buck regulator is required within a 2.6V to 5.5V input window. It is ideal for applications needing low noise and high efficiency in a small form factor. Compare against standard LDOs if higher current or lower dropout is needed.

Part Context

Part of the Maxim Integrated power management portfolio, specifically targeting mobile and wireless infrastructure. The MAX1820 series integrates control logic and power switches for simplified design.

Replacement Considerations

Check for MAX1820ZEUB-T as a pin-compatible alternative in UMAX-10 packages. Verify electrical specifications match exactly before substitution.
