MAX17020ETJ+TCCM

Overview

The MAX17020ETJ+TCCM is a dual Quick-PWM step-down power-supply controller with synchronous rectification, designed for main 5V/3.3V or auxiliary voltage rails in notebook systems. It operates from a 6V to 26V input range and provides four regulated outputs. The device features a 32-pin TQFN (5x5mm) package and functions within a -40°C to +85°C temperature range.

Feature Summary

• Dual Quick-PWM architecture for high-efficiency synchronous buck conversion
• Integrated synchronous rectification control for improved power management
• Supports multiple output voltages including 3.3V, 5V, and adjustable ranges

Applications

• Notebook power system controllers
• Main 5V/3.3V voltage rail generation
• Auxiliary voltage rail regulation

Procurement Notes

Verify the exact suffix 'TCCM' against official Analog Devices documentation, as standard tape-and-reel packaging typically uses 'T'. Confirm current availability status, as related MAX17003 variants are marked obsolete. Ensure RoHS compliance matches project requirements.

Selection Notes

Select this component for applications requiring dual synchronous buck control in compact form factors. Evaluate thermal performance within the 5x5mm TQFN footprint. Verify input voltage compatibility with the 6V-26V specification for target system architectures.

Part Context

Part of the Maxim Integrated PMIC portfolio focused on mobile computing power solutions. Designed to replace discrete MOSFET implementations by integrating gate drivers and control logic for simplified board design and reduced component count in portable electronics.

Replacement Considerations

Check for direct pin-compatible successors from Analog Devices. Consider MAX17021 series for updated feature sets if available. Verify electrical parameter equivalence before substitution.
