MAX25561ATJ/V+

LED Driver IC Overview

The MAX25561ATJ/V+ is a six-channel LED backlight driver featuring an integrated current-mode boost controller. It operates within a switching frequency range of 400kHz to 2.2MHz and includes spread spectrum functionality for noise reduction. The device supports I2C and PWM dimming interfaces, delivering up to 220mA per channel. Packaged in a 32-TQFN (5x5) case, it is designed for high-efficiency LED illumination control.

LED Driver IC Feature Summary

• Integrated current-mode boost controller with wide switching frequency range
• Supports I2C and PWM dimming for precise brightness control
• Includes spread spectrum functionality to minimize electromagnetic interference

LED Driver IC Applications

• LED illumination systems requiring multi-channel control
• Automotive display backlighting applications

LED Driver IC Procurement Notes

Verify the specific suffix 'V+' against the official Analog Devices datasheet to confirm package type and temperature grade. Ensure compatibility with required I2C addresses and dimming frequencies. Confirm availability through authorized distributors as supply status may vary by region.

LED Driver IC Selection Notes

Select this component when a compact solution for six-channel LED backlighting is required. The integrated boost controller simplifies design by reducing external component count. Consider the 400kHz to 2.2MHz frequency range for optimizing inductor size and efficiency. Verify that the 220mA output current meets the target LED string requirements.

LED Driver IC Part Context

This part belongs to the Maxim Integrated LED driver family, now under Analog Devices. It is specifically engineered for portable electronics and automotive displays where space and efficiency are critical. The integration of the boost converter distinguishes it from simple constant-current sources.

LED Driver IC Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX25560 if fewer channels are acceptable. Verify electrical parameters against the MAX25561A variant if enhanced performance specifications are needed.
