MAX1816ETM

Overview

The MAX1816ETM is a dual step-down DC-DC controller IC designed for notebook computer applications. It integrates two independent buck converters: BUCK1 serves as a CPU core regulator with dynamically adjustable output, while BUCK2 functions as an I/O supply regulator. The device operates within a wide input voltage range and supports multiple output configurations to meet varying power requirements in portable systems.

Feature Summary

• Dual step-down controller architecture for simultaneous CPU core and I/O power regulation
• Dynamically adjustable output capability for the primary CPU core converter
• Integrated protection features including overcurrent and thermal shutdown

Applications

• Notebook computer CPU core voltage regulation
• Portable system I/O supply generation
• Battery-powered mobile computing platforms

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm package integrity and pin alignment prior to installation. Check for RoHS compliance status and lead-free certification if required by assembly specifications. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent soldering defects during reflow processes.

Selection Notes

Select this component when designing dual-rail power architectures for notebook CPUs requiring independent dynamic adjustment. Evaluate input voltage ranges against battery profiles. Consider thermal dissipation requirements due to the exposed pad package. Verify compatibility with external MOSFETs and passive components for optimal efficiency and stability in high-current applications.

Part Context

The MAX1816ETM belongs to Maxim Integrated's portfolio of power management ICs for mobile computing. It complements other regulators by providing dedicated control for high-performance processors. The ETM suffix indicates a specific tape-and-reel packaging variant suitable for automated surface-mount assembly lines in consumer electronics manufacturing.
