MAX8805ZEWEBC+T

Overview

The MAX8805ZEWEBC+T is a 600mA PWM step-down converter designed for WCDMA power amplifier applications. It operates with an input voltage range of 2.7V to 5.5V and provides an adjustable output voltage from 0.4V to 5.5V. The device features a fixed switching frequency of 2MHz and delivers up to 600mA of output current. It is housed in a compact 16-WLP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated PWM step-down topology optimized for RF power amplifier efficiency
• Compact 16-WLP surface-mount packaging for space-constrained designs
• Wide input voltage compatibility supporting single-cell lithium-ion sources

Applications

• WCDMA power amplifier biasing
• RF transceiver power management
• Portable wireless communication devices

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors due to potential counterfeit risks. Confirm RoHS3 compliance status via the manufacturer's official documentation before integration. Ensure the specific suffix matches design requirements as variants may differ in thermal or electrical characteristics.

Selection Notes

Select this component when designing systems requiring high-efficiency buck conversion for RF stages. The 2MHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Verify that the required output current does not exceed the 600mA limit under all operating conditions.

Part Context

This part belongs to the MAX8805 family of specialized DC-DC converters developed by Maxim Integrated, now part of Analog Devices. These regulators are specifically engineered to meet the stringent efficiency and noise requirements of modern cellular radio frequency front ends.
