Texas Instruments TPS2330 manual Schematic of the Interface Card SLVP155

Chapter 3

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.
