MAX8805YEWEBE+T

Overview

The MAX8805YEWEBE+T is a high-efficiency, synchronous step-down DC-to-DC converter manufactured by Analog Devices Inc. under the Maxim Integrated brand. Designed for mobile and handheld applications, this device integrates two internal N-channel power switches to deliver up to 600mA of output current. It operates from an input voltage range of 2.7V to 5.5V and provides fixed output voltages of 2.5V or 3V. The converter features a programmable switching frequency of 2MHz, allowing for smaller external passive components. It is housed in a compact 16-ball WLP package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates two internal N-channel power switches for high efficiency and reduced component count
• Supports programmable switching frequencies to optimize performance for specific design requirements
• Includes thermal shutdown protection to safeguard the device during overtemperature conditions

Applications

• Power supply for WCDMA power amplifiers
• Portable electronics and handheld devices
• General-purpose low-voltage DC-to-DC conversion

Procurement Notes

Verify the exact suffix against official documentation, as variations may indicate different packaging or temperature grades. Confirm RoHS compliance status through the manufacturer's certification documents. Check for obsolescence notices or product change notifications that may affect long-term availability. Ensure the source document explicitly lists this part number variant to avoid substitution errors.

Selection Notes

Select this component when a compact solution with integrated switches is required for low-current applications. Consider the 2MHz switching frequency for minimizing inductor size. Evaluate the fixed output options against system voltage rails. Verify that the input voltage range aligns with the available power source. Assess thermal management needs based on the expected load current and ambient temperature.
