MAX8805YEWEGG+T

Overview

The MAX8805YEWEGG+T is a high-efficiency, low-noise step-down DC-to-DC converter manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 2.7 V to 5.5 V and provides a fixed output voltage of either 2.5 V or 3 V. The device delivers up to 600 mA of output current and integrates a 2 MHz switching frequency for compact external component sizing. Packaged in a 16-ball Wafer Level Package (WLP), it supports surface-mount installation and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a 2 MHz PWM step-down converter topology for efficient power conversion
• Features a compact 16-ball WLP package suitable for space-constrained designs
• Supports fixed output voltages of 2.5 V or 3 V with up to 600 mA load capability

Applications

• Power supply for WCDMA power amplifiers
• Portable communication devices requiring low noise regulation
• Battery-powered systems needing efficient step-down conversion

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the MAX8805 family. Confirm availability status, as specific variants may be discontinued or subject to limited distribution. Ensure compatibility with required output voltage options (2.5 V or 3 V) and packaging formats before procurement.

Selection Notes

Select this component when designing circuits that require a small footprint and low noise performance for RF applications. The fixed 2 MHz switching frequency allows for the use of small inductors and capacitors. Verify that the required output voltage matches the specific variant available, as the part number indicates fixed outputs rather than adjustable ones.

Part Context

This component belongs to the MAX8805 series of high-efficiency, low-noise step-down converters designed primarily for powering RF sections in mobile handsets. The series is characterized by its ability to provide clean power to sensitive analog loads while maintaining high efficiency over a wide input voltage range.
