Procurement Notes

Verify the specific suffix variant against the official Renesas datasheet to ensure compatibility with target voltage and current requirements. Confirm AEC-Q100 Grade 2 qualification status if automotive reliability is required. Check for any recent product discontinuation notices or last-time-buy notifications from the manufacturer. Ensure the BGA package dimensions and pitch match the PCB layout specifications. Validate that the selected part number corresponds to the correct tape-and-reel carrier type for automated assembly processes.

Selection Notes

Select this component when designing power supplies for automotive processors requiring high transient response and compact solution size. The integrated FETs reduce external component count compared to discrete solutions. Consider the 0.8mm pitch BGA package for space-constrained designs. Ensure the application requires an input voltage within the 2.8V to 5.5V range. Verify that the software stack supports the necessary I2C/SPI commands for DVC and phase shedding control.
