DA9141-XXF71

Overview

The DA9141-XXF71 is a quad-phase DC-DC converter from the Renesas DA9141 series, designed for high-current applications. It delivers a continuous output current of 25A and a peak current of 40A. The device features an output voltage range up to 1.3V, with selectable base voltages of 0.8V or 0.85V via GPIO. It operates within a temperature range of -40°C to +125°C and utilizes an I2C interface with address 0xD4. Packaged in a 60-pin FCBGA format, it supports SMD/SMT installation.

Feature Summary

• Quad-phase architecture for high efficiency
• GPIO-selectable output voltage configuration
• I2C programmable control interface
• Extended industrial temperature operation

Applications

• AI accelerator card power delivery systems
• Multi-phase power systems for high-density designs
• Low-voltage high-current load regulation

Procurement Notes

Verify component authenticity through authorized channels due to limited supply status. Confirm package integrity and moisture sensitivity handling prior to assembly. Ensure compatibility with existing PCB footprint and thermal management requirements. Validate I2C addressing and GPIO configurations against system design specifications before integration.

Selection Notes

Select this component for applications requiring sustained high current delivery above 20A. Consider the FCBGA-60 package constraints for layout routing. Evaluate thermal dissipation needs given the 2.43W power dissipation rating. Verify that the 0.8V/0.85V selectable output aligns with target core voltage requirements.
