MAX1820ZEUB-TG069

Overview

The MAX1820ZEUB-T is a high-efficiency, synchronous step-down DC/DC converter designed for WCDMA applications. It delivers up to 600mA of output current with an input voltage range of 2.6V to 5.5V. The device operates at a fixed switching frequency of 1MHz and provides an adjustable output voltage from 400mV to 3.4V. It features a uMAX-10 surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Synchronous rectification architecture ensures high conversion efficiency across the load range.
• Integrated power switch eliminates external inductor requirements for compact designs.
• Fixed 1MHz switching frequency allows for small passive component selection.

Applications

• WCDMA base station power supplies
• Portable communication equipment regulation
• General-purpose low-voltage DC/DC conversion

Procurement Notes

Verify the specific suffix 'G069' against official Analog Devices documentation, as standard datasheets typically list 'MAX1820ZEUB-T'. Confirm RoHS compliance status and lead times directly with authorized distributors, noting that availability may be restricted or subject to factory special orders.

Selection Notes

Select this component when a compact, single-output buck regulator is required for mobile infrastructure. Ensure the load current does not exceed 600mA and the input voltage remains within the 2.6V to 5.5V window. Consider thermal performance in the uMAX-10 package for high-density layouts.

Part Context

This part belongs to the MAX1820Z family of synchronous regulators optimized for wireless communications. It shares topology with other Maxim Integrated buck converters but is specifically tuned for the efficiency and noise requirements of cellular base stations and portable devices.
