MAX77874CEWM+T

Overview

The MAX77874CEWM+T is a quad-phase core buck regulator manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 2.7 V to 4.8 V and provides a single output adjustable from 250 mV to 1.3 V. The device delivers up to 16 A of output current with a switching frequency of 2 MHz. It features a WLP-48 package, supports SMD/SMT mounting, and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Uncoupled quad-phase architecture for high current delivery
• Integrated shutdown control capability
• Ultra-low quiescent current operation

Applications

• Mobile processor core power supplies
• Smartphone baseband power regulation
• Portable computing system voltage rails

Procurement Notes

Verify the specific suffix 'CEWM' against official manufacturer documentation to confirm exact thermal grade and packaging specifications. Confirm availability status as distribution channels may indicate limited supply or discontinuation for this specific variant. Ensure compatibility with required PCB footprint dimensions for the WLP-48 package.

Selection Notes

Select this component when designing systems requiring high transient response and significant current capacity in a minimal footprint. The quad-phase topology allows for efficient power conversion at high loads while maintaining low ripple. Verify that the input voltage source remains stable within the specified 2.7 V to 4.8 V window for optimal performance.

Part Context

This part belongs to the MAX77874 series of high-efficiency buck regulators designed for mobile applications. It is distinct from other Maxim Integrated PMICs by its specific four-phase configuration and wafer-level packaging, targeting dense board layouts common in modern handheld devices.

Replacement Considerations

Consult official cross-reference lists for verified substitutes such as the MAX77874BEWM+T. Ensure any replacement maintains identical pinout and electrical characteristics to avoid redesigning the power stage.
