MAX8805YEWEAE+T

Overview

The MAX8805YEWEAE+T is a high-efficiency, low-noise step-down DC-to-DC converter manufactured by Analog Devices Inc. under the Maxim Integrated brand. Designed for RF and mixed-signal applications, this device integrates a 600mA power switch within a compact WLP-16 package. It operates with an input voltage range of 2.7V to 5.5V and provides fixed output voltages of 2.5V or 3V. The converter features a switching frequency of 2MHz, enabling the use of small external components while maintaining stable performance across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a 600mA power switch for compact board space utilization
• Optimized for low noise and high efficiency in RF power amplifier supply
• Fixed output voltage options ensure precise regulation for sensitive loads

Applications

• WCDMA Power Amplifier (PA) power supply
• RF transceiver biasing circuits
• Mixed-signal system core voltage generation

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeit risks. Confirm RoHS compliance status and specific lot traceability requirements before integration. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage during assembly processes.

Selection Notes

Select this component when designing power supplies for RF front-end modules requiring low ripple and fast transient response. The fixed output configuration simplifies design but limits flexibility compared to adjustable regulators. Evaluate thermal dissipation capabilities within the WLP-16 package against total system power budget constraints.

Part Context

This part belongs to the MAX8805Y series, which focuses on specialized voltage regulation for wireless communication systems. Unlike general-purpose buck converters, these devices are tuned specifically for the noise and load-line requirements of cellular baseband and RF sections.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Check for obsolescence notices as the product lifecycle status may indicate end-of-life conditions.
