Full-Featured –48-V Hot Swap Power Manager
2.2 The Full-Featured –48-V Hot Swap EVM Jumper Card
2.2.1 Description
The EVM jumper card is used to apply the –48-V supply voltage, present at the input banana jacks, to the supply
input of the main board’s plug-in side. Inserting and removing the jumper card into and out of the main board
P1 connector simulates hot swap events. There are no components mounted on the jumper card; it simply
makes the point-to-point connections to apply input power to the plug-in electronics. This mechanism allows the
EVM main board, which may have several scope probes and meter leads connected to it during use, to remain
stationary on the user’s bench.
A pictorial of the jumper card top layer is shown in Figure 3.
