MAX25601DAUI/V+

LED Driver IC Overview

The MAX25601DAUI/V+ is a high-efficiency, synchronous step-down DC-DC converter from Analog Devices. It integrates two N-channel power switches and operates with an input voltage range of 3.8V to 36V. The device supports output voltages down to 0.8V with a maximum output current capability determined by external components. It features adjustable switching frequencies up to 2.2MHz, enabling the use of small passive components. Integrated protections include overcurrent, thermal shutdown, and undervoltage lockout.

LED Driver IC Feature Summary

• Integrated synchronous rectification for improved efficiency
• Wide input voltage range suitable for industrial applications
• High-frequency operation reduces passive component size
• Comprehensive protection mechanisms ensure reliable operation

LED Driver IC Applications

• Industrial automation controllers
• Telecommunications infrastructure
• Point-of-load regulation systems

LED Driver IC Procurement Notes

Verify the specific suffix 'V+' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the DAUI package marking matches the physical component received. Ensure ordering documents explicitly reference the full part number to avoid confusion with non-V variants or different package options.

LED Driver IC Selection Notes

Select this component when a wide input voltage range and high efficiency are required in a compact footprint. Consider the thermal performance under maximum load conditions. Evaluate the need for external compensation versus internal stability. Verify that the desired output voltage falls within the supported range of the internal reference.

LED Driver IC Part Context

This part belongs to the MAX256xx family of synchronous buck converters designed for robust industrial environments. It replaces older discrete solutions or less integrated regulators. The DAUI package offers a thermally enhanced solution for space-constrained designs. It complements other Maxim Integrated power management products in system-level designs.

LED Driver IC Replacement Considerations

Direct pin-to-pin replacements may include other MAX256xx variants with adjusted feature sets. Verify compatibility regarding switching frequency ranges and control loop stability. Check if alternative packages offer equivalent thermal performance. Consult official substitution guides for confirmed equivalents.
