MAX25600AUI/V+T

LED Driver IC Overview

The MAX25600AUI/V+T is a synchronous high-voltage multi-topology LED lighting driver IC manufactured by Analog Devices Inc. It integrates four channels and supports step-down (buck), step-up (boost), and other configurations for driving LEDs. The device operates with an input voltage range of 4 V to 60 V and features analog and PWM dimming capabilities. Packaged in a 28-TSSOP-EP format, it is designed for automotive front light applications requiring flexible topology control.

LED Driver IC Feature Summary

• Integrates four independent output channels for multi-LED configuration
• Supports synchronous buck and boost topologies within a single device
• Enables precise brightness control through analog and pulse-width modulation dimming

LED Driver IC Applications

• Automotive front lighting systems
• High-brightness LED matrix arrays
• Multi-channel LED backlighting solutions

LED Driver IC Procurement Notes

Verify the specific suffix and tape-and-reel specifications against the official datasheet before ordering. Confirm that the 28-TSSOP-EP package matches your PCB footprint requirements. Ensure compatibility with your system's thermal management design due to the integrated power stage. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

LED Driver IC Selection Notes

Select this component when a single IC must handle multiple LED strings with varying voltage requirements. It is suitable for designs needing both buck and boost regulation without external discrete switches. Consider the 28-pin thermal pad package for efficient heat dissipation in compact automotive enclosures. Verify that the required dimming frequency aligns with the controller's analog and PWM inputs.

LED Driver IC Part Context

This part belongs to the MAX25600 family of high-voltage LED drivers from Maxim Integrated, now part of Analog Devices. The series focuses on automotive-grade solutions for complex lighting architectures. Similar parts in the lineup include the MAX25601 and MAX25603, which offer different channel counts or topology variations. The MAX25600 specifically addresses applications requiring four-channel flexibility.

LED Driver IC Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX25601DAUI/V+T if fewer channels are acceptable. Evaluate the MAX25603AUI/V+ for different switching configurations. Ensure any substitute maintains the 60 V maximum input rating and automotive temperature range.
