MAX17020ETJ+

Overview

The MAX17020ETJ+ is a dual Quick-PWM step-down controller manufactured by Analog Devices Inc./Maxim Integrated. It integrates two synchronous buck controllers, a low-power LDO, and an RTC regulator within a single package. The device supports input voltages from 6V to 24V and operates across a temperature range of -40°C to +85°C. It features a precision 1.2V reference, power-good indicators, and inductor current monitoring capabilities.

Feature Summary

• Dual Quick-PWM step-down control architecture for efficient power conversion
• Integrated low-power LDO and real-time clock (RTC) regulator
• Inductor current monitoring functionality for enhanced system protection

Applications

• Power supplies
• Industrial systems requiring multi-rail power management
• Embedded systems with RTC requirements

Procurement Notes

Verify the specific suffix ETJ+ against official Analog Devices documentation to confirm the TQFN-32 package and lead-free status. Ensure compatibility with your PCB footprint design. Confirm active status through authorized distributors as availability may vary by region.

Selection Notes

Select this component when a compact solution for dual synchronous buck regulation is required alongside auxiliary power rails. The integrated LDO and RTC regulator reduce external component count. Verify that the 6V to 24V input range matches your system supply and that the thermal performance of the TQFN-32 package suits your enclosure constraints.

Part Context

This part belongs to the Maxim Integrated portfolio, now part of Analog Devices. It is designed for applications needing high-efficiency DC-DC conversion with minimal external components. The integration of multiple regulators simplifies board layout and reduces overall system cost compared to discrete solutions.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic equivalents may not match the integrated LDO/RTC features or Quick-PWM timing characteristics.
