MAX17003ETJ+

Special Purpose Regulators Overview

The MAX17003ETJ+ is a quad-output main power supply controller designed for notebook computer systems. It operates within an input voltage range of 6V to 26V and provides regulated outputs of 3.3V, 5V, and adjustable voltages between 2V and 5.5V. The device is housed in a 32-TQFN (5x5mm) package with an exposed pad. It supports surface-mount installation and functions reliably across a temperature range of -40°C to +85°C. This component serves as a central management unit for multi-rail power architectures in portable computing devices.

Special Purpose Regulators Feature Summary

• Manages four distinct output rails for comprehensive system power distribution
• Optimized specifically for notebook computer power architecture requirements
• Operates from standard laptop battery voltage ranges up to 26V

Special Purpose Regulators Applications

• Notebook computer main power supply control
• Multi-rail DC-DC converter systems
• Portable computing device power management

Special Purpose Regulators Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited supply constraints. Confirm exact packaging options such as cut tape or reel quantities with authorized distributors. Ensure compatibility with existing design specifications before procurement. Check for alternative sources if original manufacturing supply is restricted.

Special Purpose Regulators Selection Notes

Select this controller when designing power systems for notebooks requiring four synchronized output rails. Ensure the input voltage source falls within the 6V to 26V operational window. Verify that the thermal performance of the 32-TQFN package meets the application's heat dissipation needs. Confirm that the required output voltages align with the fixed 3.3V and 5V rails plus the adjustable range.

Special Purpose Regulators Part Context

This part belongs to the Maxim Integrated line of power management integrated circuits, now under Analog Devices Inc. It is categorized under special-purpose regulators and switching controllers. The device addresses the complex power sequencing and monitoring needs typical in mobile computing platforms, replacing discrete logic solutions with an integrated controller approach.

Special Purpose Regulators Replacement Considerations

Check for direct pin-to-pin replacements within the same family. Review updated datasheets for any functional improvements in successor models. Verify that alternative components support the same four-output configuration and input voltage range.
