MAX20056BAUGB/V+

LED Driver IC Overview

The MAX20056BAUGB/V+ is an integrated, six-channel high-brightness LED driver designed for automotive displays. It supports boost, buck-boost, and SEPIC converter topologies with a switching frequency of 2.2 MHz. The device operates on a supply voltage range of 4.5 V to 42 V, delivering up to 120 mA per channel at an output voltage of 4.8 V to 5.2 V. It features very wide PWM dimming ratios and phase-shifting capabilities to minimize electromagnetic interference.

LED Driver IC Feature Summary

• Integrates six independent high-current channels for driving multiple LED strings
• Supports flexible power conversion topologies including boost, buck-boost, and SEPIC
• Provides very wide PWM dimming ratio control for precise brightness adjustment
• Includes phase-shifting functionality to reduce system-wide electromagnetic interference

LED Driver IC Applications

• Automotive display backlighting systems
• Multi-string LED driver circuits
• High-efficiency lighting applications requiring noise suppression

LED Driver IC Procurement Notes

Verify the specific suffix 'V+' indicates RoHS compliance and lead-free status as per Analog Devices standards. Confirm the TSSOP-EP package variant matches your PCB footprint requirements. Ensure the component meets AEC-Q100 automotive qualification grades if required for your specific vehicle application tier. Cross-reference the manufacturer date code to ensure freshness for sensitive soldering processes.

LED Driver IC Selection Notes

Select this component when designing automotive display drivers requiring high efficiency and minimal external components. The 2.2 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. The integrated nature reduces board space, making it suitable for compact dashboard or infotainment units. Consider the 42 V supply tolerance for robust operation in noisy automotive electrical environments.

LED Driver IC Part Context

This part belongs to the Maxim Integrated LED driver family, now under Analog Devices Inc. It is specifically engineered for automotive-grade reliability, meeting AEC-Q100 standards. The device replaces discrete solutions by integrating control logic and power stages, simplifying the design of complex multi-zone lighting systems found in modern vehicles.

LED Driver IC Replacement Considerations

Check for direct pin-compatible upgrades within the MAX20056 series. Verify that alternative parts support the same 42 V input range and 120 mA output current. Ensure any substitute maintains the 2.2 MHz switching frequency to preserve filter component sizes.
