Description
This EVM enables full evaluation of the TPS25910 device. Refer to the schematic shown in
Ethernet power is applied at J1/J2 while J3/J4 provide the output connection to the load. D1, C6 and C1
provide input protection for the TPS25910 (U1). S1 allows U1 to be enabled or disabled with R3/R5
providing a means for an external turn-on threshold. Circuit faults can be observed at TP6.

Turn on or inrush slew rate control can be enabled by installing a shunt on J5 which connects C5 to
GATE. For blocking applications, Q1 can be installed and R4 removed.
