Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm pinout compatibility and functional parameters. Confirm automotive grade certification status and RoHS compliance requirements prior to integration. Check for any recent obsolescence notices or recommended new designations as OTP parts may become non-cancelable once finalized. Ensure supply chain availability aligns with project timelines due to potential limited stock situations.

Selection Notes

Select this component when designing for automotive applications requiring dual independent buck converters within a single package. It is suitable for powering multicore SoCs, GPUs, or FPGAs that demand high transient response and low output ripple. Consider the VFBGA-66 footprint constraints and thermal dissipation requirements during PCB layout. Verify that the input voltage source falls within the 2.8V to 5.5V range for optimal operation.
