MAX77839BEWL+T

Overview

The MAX77839BEWL+T is a low quiescent current mini buck converter manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 2.5 V to 5.5 V and delivers up to 2.5 A of output current. The device utilizes a WLP-10 package and supports switching frequencies from 600 kHz to 2.4 MHz. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a synchronous buck topology for high efficiency in compact designs
• Features adaptive on-time control for fast transient response
• Includes programmable soft-start and frequency options

Applications

• Portable consumer electronics
• Battery-powered devices
• Industrial equipment power distribution

Procurement Notes

Verify the specific suffix 'BEWL' against official datasheets to confirm pinout and thermal characteristics. Confirm RoHS compliance status via manufacturer documentation before integration. Ensure ESD handling protocols are followed during assembly due to the WLP package type.

Selection Notes

Select this component when system design requires a small footprint combined with moderate current capability. Evaluate the required output voltage against the adjustable feedback network. Consider the operating frequency trade-offs between efficiency and external component size.

Part Context

This part belongs to the Maxim Integrated portfolio, now integrated into Analog Devices. It serves as a power management solution for applications requiring efficient step-down conversion from single-cell lithium-ion or lithium-polymer battery sources.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic equivalents may differ in thermal performance or control loop stability.
