Description and Testing
Figure 2–1 shows the schematic of the TPS2080EVM (SLVP196). The sche-
matic shows two connectors (J1 and J2). J1 is used to connect input supply
voltages and external enable signals (EN1 and EN2). EN1 is used to externally
enable V
O
1 and En2 is used to externally enable V
O
2.
Note:
When external enable terminals are used, SW1 and SW2 must be on the
Disable positions marked on the EVM. For normal operation, EN1 and EN2
should be floating.
When testing the EVM, set slide switch SW1 (and/or SW2) on the EVM to
Enable V
O
1 (and/or Enable V
O
2) as marked on the board.
Several capacitors and connectors are only required for evaluation purposes
and are not necessary for the hot-swap applications. Refer to the applicable
data sheets to optimize your designs.
The bill of materials (BOM) for the TPS2080EVM is shown in Table 2–1.
