The TIDA-010958 is a radiation-hardened synchronous buck power reference design intended for the AMD® Versal® AI Core XQRVC1902 core rail. The design is optimized for a 12V input operation to generate a 0.8V output voltage and maximum 80A output current. This compact power design delivers high current while following the tight tolerance requirements of the FPGA. This power design, combined with the Versal® AI Core XQRVC1902, provides satellites with the accuracy, reliability, and efficiency needed to carry out different missions. TIDA-010958 has radiation-hardened devices and the passive components are compliant with MIL standard MIL-STD-55681 (or equivalent) where available. Otherwise, an equivalent value and component size was substituted.
