MAX8805ZEWECE+T

Overview

The MAX8805ZEWECE+T is a high-efficiency, 600mA PWM step-down converter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with an input voltage range of 2.7V to 5.5V and provides a fixed output voltage of 3V. The device features a switching frequency of 2MHz and supports an output current of 600mA. It is housed in a compact 16-WLP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a 600mA power switch for efficient step-down conversion
• Utilizes a fixed 2MHz switching frequency to minimize external component size
• Includes internal compensation for simplified circuit design

Applications

• Portable consumer electronics
• Battery-powered devices
• WCDMA PA power supplies

Procurement Notes

Verify the specific suffix 'E' against official datasheets to confirm pinout and thermal characteristics. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributors. Check for obsolescence notices as this series may have discontinuation updates. Ensure the WLP-16 package availability matches your assembly requirements.

Selection Notes

Select this component when a fixed 3V output is required from a single-cell lithium battery source. The 2MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the 600mA load current does not exceed the device's continuous rating under maximum ambient temperature conditions.
