Schematics of the EVM and the Interface Card
The evaluation kit includes two boards: one is the hot-swappable
TPS2330EVM-184 48-V hot-swap EVM (SLVP184 board) where the
TPS2330 controls voltage ramp-up and reduces inrush current during hot-plug
events; the other is an interface card (SLVP155 board) that supplies power to
the 48-V hot-swap board.
Figures 3–1 and 3–2 show the schematic of the interface card and the
schematic of the hot-swappable EVM respectively.
