MAX8836ZEREEE+T

Overview

The MAX8836ZEREEE+T is a synchronous step-down switching controller manufactured by Analog Devices under the Maxim Integrated brand. It integrates a 1.2A power switch and operates as a PWM DC-DC converter. The device utilizes a fixed 1.5MHz switching frequency to minimize external component size. It features an adjustable output voltage range from 0.8V to 5.5V, controlled via an external resistor divider. The controller includes comprehensive protection mechanisms such as cycle-by-cycle current limit, thermal shutdown, and undervoltage lockout. It is housed in a compact 6-pin SOT23 package suitable for space-constrained portable applications.

Feature Summary

• Integrates a high-efficiency synchronous rectification architecture with a built-in 1.2A power MOSFET.
• Operates at a fixed 1.5MHz switching frequency to reduce passive component footprint.
• Provides robust protection through integrated cycle-by-cycle current limiting and thermal shutdown circuitry.

Applications

• Portable battery-powered consumer electronics
• Handheld communication devices
• Personal digital assistants (PDAs)
• Wireless peripherals

Procurement Notes

Verify the specific suffix ZEREEE against the official datasheet to confirm pin compatibility and thermal characteristics. Confirm RoHS compliance status directly with the manufacturer documentation. Ensure the supply chain source provides valid traceability for the +T reel packaging format. Cross-reference the ordering information with the latest Analog Devices product selector guide to avoid obsolete variants.

Selection Notes

Select this component when a compact solution for low-to-medium current loads is required. The fixed frequency operation simplifies filter design compared to variable frequency controllers. Consider the 1.2A continuous current capability relative to the peak load requirements of the target application. Evaluate the input voltage range compatibility with the system's power source before finalizing the design.

Part Context

This part belongs to the MAX8836Z series of synchronous buck converters designed for efficiency and small size. It represents a class of power management ICs optimized for mobile applications where battery life and board space are critical constraints. The series focuses on integrating power switches to reduce external bill of materials.

Replacement Considerations

Consult the official Analog Devices cross-reference tool for verified substitutes. Direct replacements must match the 1.2A current rating, 1.5MHz frequency, and SOT23-6 package. Verify that alternative parts support the same 0.8V minimum output voltage requirement.
