MAX25610AATEY+T

LED Driver IC Overview

The MAX25610AATEY+T is a synchronous LED driver IC from Analog Devices Inc./Maxim Integrated, designed for high-power LED applications. It features a single output channel with a switch current rating of 20mA and supports both step-down (buck) and step-up (boost) topologies. The device operates within a supply voltage range of 4.5V to 36V, delivering an output voltage up to 35V. It integrates internal power switches and supports switching frequencies of 400kHz, 1MHz, 1.6MHz, and 2.1MHz. Dimming control is available via analog or PWM signals. The component is housed in a 16-pin WQFN package with an exposed pad and is rated for operation between -40°C and 125°C.

LED Driver IC Procurement Notes

Verify the exact suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'A' grade designation meets specific automotive temperature and performance requirements. Check RoHS3 compliance status as per the manufacturer's latest documentation. Ensure the 16-WQFN footprint matches your PCB layout constraints. Validate availability through authorized distributors due to potential supply fluctuations.

LED Driver IC Selection Notes

Select this model for applications requiring a single-channel driver with integrated switches. Choose based on the need for both buck and boost capabilities in one device. Consider the 20mA switch current limit for lower-power LED strings. Evaluate the 16-pin WQFN package for space-constrained designs. Verify compatibility with existing analog or PWM dimming control schemes.

LED Driver IC Part Context

This component belongs to the MAX25610 series, which includes variants like the MAX25610AATEY+ and MAX25610BATEY+. The series is part of Maxim Integrated's portfolio of LED drivers for automotive and industrial lighting. It shares functional similarities with the MAX25614 series but differs in output current capacity and pin configuration. The MAX25610 focuses on mid-power applications compared to higher-current counterparts.

LED Driver IC Replacement Considerations

Direct substitutes include other MAX25610 variants such as MAX25610AATEY+ (non-tape/reel). Cross-reference with MAX25614 series if higher current is acceptable. Verify pinout compatibility before substitution.
