MAX25601ATJ/VY+T

LED Driver IC Overview

The MAX25601ATJ/VY+T is a synchronous boost and synchronous buck LED lighting driver IC manufactured by Analog Devices Inc./Maxim Integrated. It features an integrated high-side and low-side gate drivers with bootstrap diode and capacitor integration, reducing external component count. The device operates in a TQFN-CU-32 package and supports PWM dimming for precise control.

LED Driver IC Feature Summary

• Integrates high-side and low-side gate drivers with bootstrap components to minimize external parts
• Supports synchronous boost and synchronous buck topologies for flexible LED driving
• Enables precise LED current regulation through PWM dimming capabilities

LED Driver IC Applications

• Automotive LED headlight systems
• High-voltage HB LED controllers
• Infotainment system backlighting

LED Driver IC Procurement Notes

Verify the exact suffix (e.g., ATJ/VY+T) against the manufacturer's official datasheet to ensure correct pinout and thermal pad configuration. Confirm RoHS compliance status and AEC-Q100 qualification if automotive grade is required. Check for limited supply status as availability may vary by region.

LED Driver IC Selection Notes

Select this component for applications requiring integrated power stage solutions with reduced bill of materials. Ensure the input voltage range and output current requirements align with the specific boost or buck topology needs. Verify that the TQFN-CU-32 package fits within the available PCB area and thermal constraints.

LED Driver IC Part Context

This part belongs to the MAX25601 family of LED lighting drivers designed for high-efficiency power conversion. It is distinct from similar models like the MAX25611 or MAX25614 which may offer different current ratings or communication interfaces such as I2C. The ATJ/VY+T variant specifically denotes the automotive-grade temperature range and packaging style.

LED Driver IC Replacement Considerations

Direct substitutes include other members of the MAX25601 family such as MAX25601AATJ/VY+T or MAX25601CATJ/VY+T, provided the electrical specifications and pin compatibility match the design requirements.
