MAX1994ETM

Special Purpose Regulators Overview

The MAX1994ETM is a dual-output synchronous buck switching regulator IC from Analog Devices/Maxim Integrated. It operates with an input voltage range of 2V to 28V and provides two adjustable outputs, supporting 0.7V-2V or 1V-5.5V ranges. The device utilizes a 48-WFQFN exposed pad package (7x7mm) for surface mount installation. It features integrated synchronous rectification for high efficiency and minimal heat generation. The component supports operation across an extended temperature range of -40°C to +100°C.

Special Purpose Regulators Feature Summary

• Dual-output regulation capability for independent power rails
• Synchronous rectification topology for enhanced efficiency
• Wide input voltage tolerance up to 28V
• Exposed pad thermal design for improved heat dissipation

Special Purpose Regulators Applications

• Telecommunications infrastructure power systems
• Industrial control equipment power distribution
• Embedded system central processing unit core voltage regulation

Special Purpose Regulators Procurement Notes

Verify the specific suffix variant required, as availability may differ between tube and tape-and-reel packaging options. Confirm RoHS compliance status through official documentation prior to integration. Check for end-of-life notifications or discontinuance alerts from the manufacturer to ensure long-term supply stability for production planning.

Special Purpose Regulators Selection Notes

Select this component when dual isolated or non-isolated low-voltage rails are required from a single higher-voltage source. Ensure the load current requirements for both outputs fall within the device's continuous current ratings. Verify that the PCB layout can accommodate the 48-pin QFN footprint and provide adequate thermal relief for the exposed pad to maintain junction temperatures within safe operating limits.

Special Purpose Regulators Part Context

This part belongs to the Maxim Integrated power management portfolio, specifically designed for applications requiring efficient multi-rail power conversion. It complements other regulators in the series by offering integrated control loops for both channels, reducing external component count compared to discrete solutions.

Special Purpose Regulators Replacement Considerations

Consult official cross-reference lists for direct pin-compatible alternatives. Evaluate functional equivalents from the same manufacturer family that may offer updated packaging or enhanced thermal performance while maintaining compatible electrical specifications.
