2 STAR-Tiger Power-Supply Design

The power-supply board in the STAR-Tiger unit provides the primary power rails to the Xilinx KU060 FPGA being used to implement the routing switch. The STAR-Tiger power-supply design is shown in Figure 2-6, along with a photograph of the board in Figure 2-2. The STAR-Tiger power-supply board uses the following space-rated power-supply devices from Texas Instruments: TPS7H2201-SP, TPS50601A-SP, TPS7H4001-SP, TPS7H1101A-SP, and the TPS7A4501-SP. All these devices are class V devices and qualified up to Total Ionizing Dose (TID) = 100 krad(Si) and LET = 75 MeV-cm²/mg.
