MAX8836ZEWEEE+

Overview

The MAX8836ZEWEEE+ is a synchronous step-down switching regulator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates high-side and low-side N-channel MOSFETs to deliver up to 1.2A of output current. The device operates from an input voltage range of 2.7V to 5.5V and features a fixed internal frequency of 1.5MHz. It utilizes PWM control for efficient power conversion and includes comprehensive protection mechanisms such as overcurrent, thermal shutdown, and undervoltage lockout.

Feature Summary

• Integrates high-side and low-side N-channel MOSFETs for compact design
• Fixed 1.5MHz switching frequency minimizes external component size
• Includes adaptive on-time control for fast transient response
• Features comprehensive protection against overcurrent and thermal overload

Applications

• Portable electronics powered by single-cell lithium-ion batteries
• Wireless communication devices requiring efficient power management
• Embedded systems with strict space constraints
• Industrial control modules operating from 5V supplies

Procurement Notes

Verify the specific suffix ZEWEEE+ against official datasheets to confirm package type and temperature grade. Confirm availability status directly with authorized distributors as supply conditions may vary. Ensure compatibility with required input voltage ranges and load currents before finalizing procurement decisions.

Selection Notes

Select this component when a compact solution with integrated power switches is required. It is suitable for applications needing up to 1.2A output current from a 5V source. Consider the fixed 1.5MHz frequency for balancing efficiency and component size. Verify that the thermal performance meets system requirements under maximum load conditions.

Part Context

This part belongs to the MAX8836 family of synchronous buck converters designed for portable applications. It shares core architecture with other members but differs in packaging and specific electrical characteristics defined by the suffix. The series is optimized for high efficiency and small footprint in mobile and handheld devices.

Replacement Considerations

Consult official substitution guides for compatible parts within the MAX8836 or MAX8837 families. Verify pin compatibility and electrical specifications before replacing. Generic equivalents may not match the integrated MOSFET characteristics or protection features.
