The EVM supports two versions (Auto-Retry and Latched) of the devices on two Channels (CH1 and CH2, respectively). Input power is applied at J1 (CH1) and, J5 (CH2) while J2 and (CH1)/J6 (CH2) provide the output connection to the load. Refer to the schematic in Figure 1, and EVM test setup in Figure 2. D1/C1(CH1), D5/C9 (CH2) provide input protection for the TPS25921X (U1 and U2, respectively) while D2/C2-C6 (CH1), D6/C10-C14 (CH2) provide output protection and inrush current demand from the load. S1 and S2 allow U1 and U2, respectively, to be RESET or disabled. A power good (PG) indicator is provided by D3, D7 for CH1 and CH2, respectively, and circuit faults can be observed with D4. Scaled channel current can be monitored at TP10 and TP20 with a scale factor of approximately 1 V/A. Table 1.
