MAX17103ETJ+

Overview

The MAX17103ETJ+ is a quad step-down regulator from Analog Devices, featuring gangable outputs and ultralow EMI performance. It integrates four independent buck converters within a single package to provide efficient power management for portable electronics. The device operates with a supply voltage range of 2.3V to 5.5V and supports an operating temperature range from -40°C to +85°C. Packaged in a compact 32-TQFN (5x5) surface-mount format, it is designed for applications requiring multiple regulated rails with minimal electromagnetic interference.

Feature Summary

• Integrates four independent step-down regulators in a single package
• Features gangable outputs for combined current capability
• Provides ultralow electromagnetic interference performance

Applications

• LCD Monitor power systems
• Notebook Display power architectures

Procurement Notes

Verify the specific suffix and tape-and-reel or tube packaging options directly with authorized distributors. Confirm that the 32-TQFN footprint matches your PCB design requirements. Ensure thermal dissipation capabilities are adequate for your intended load conditions within the specified temperature range.

Selection Notes

Select this component when multiple low-voltage rails are required from a single input source. The integrated nature reduces board space compared to discrete solutions. Consider the ultralow EMI feature if the application is sensitive to noise. Verify that the total output current requirements across all channels can be met by the individual regulator limits.

Part Context

This part belongs to the MAX17103 family of power management ICs. It is manufactured by Analog Devices Inc., formerly Maxim Integrated. The device is categorized under specialized PMICs for portable applications. It complements other linear and switching regulators in the company's portfolio for complete system power solutions.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify that any substitute offers equivalent gangable output functionality and similar EMI characteristics. Ensure the replacement maintains the 2.3V to 5.5V input voltage range and 32-TQFN package dimensions.
