MAX1632EAI+T

Overview

The MAX1632EAI+T is a highly integrated power management IC (PMIC) designed for notebook computers. It features three outputs: two switching buck regulators and one low-dropout linear regulator (LDO). The device operates with an input voltage range of 4.2V to 30V and includes internal sequencing control. It utilizes a 28-SSOP package and supports switching frequencies between 200kHz and 300kHz.

Feature Summary

• Integrates dual buck converters and a single LDO in one package
• Includes internal sequencing logic for multi-rail power systems
• Designed specifically for low-noise applications in portable computing

Applications

• Notebook computer power supplies
• Point-of-load DC/DC conversion
• Multi-output power management systems

Procurement Notes

Verify the specific suffix 'EAI' against the official Analog Devices datasheet to confirm pinout, temperature grade, and RoHS compliance status. Ensure the '+T' designation matches the required tape-and-reel packaging format for your assembly line. Cross-reference the manufacturer's latest lifecycle notifications to confirm current production status.

Selection Notes

Select this component when a compact solution for notebook power rails is required. It combines switching efficiency with LDO noise performance. Verify that the 4.2V to 30V input range covers your system's battery or adapter specifications. Confirm that the 28-SSOP footprint fits your PCB layout constraints.

Part Context

This part belongs to the MAX1632 family of PMICs from Maxim Integrated, now part of Analog Devices. These devices are engineered to simplify power design in mobile platforms by reducing component count. The series typically targets applications requiring multiple regulated voltages from a single high-voltage source.

Replacement Considerations

Check for direct substitutes within the MAX1632 family, such as the MAX1632AEAI+T, ensuring functional equivalence. Verify compatibility with any legacy MAX1632 variants before substitution.
