Procurement Notes

Verify the specific ordering suffix XTMA1 against official Infineon documentation to confirm reel packaging and tape-and-reel specifications. Confirm that the NRND status does not impact long-term availability requirements for your production timeline. Ensure compatibility with existing PCB footprints for the 40-pin VQFN package before finalizing procurement decisions.

Selection Notes

Select this component when designing for Intel VR12.5 or VR13 processors requiring a compact dual-output solution. The 1+1 phase configuration suits applications needing two distinct voltage rails with minimal board space. Consider the industrial temperature rating if the operating environment exceeds standard commercial limits. Verify that the 3 V to 3.6 V input range aligns with your system's primary power distribution network.
