3 TPS7H4001QEVM-CVAL Initial Setup

This section provides the test instruments required and the connections to the EVM as shown in Figure 2.

1. Remove Jumper J9 so that enable pins to all devices is no longer grounded.
2. Input DC power supply
   1. Set for 5-V DC, 30-A current limit
   2. Connect positive output of DC supply to pin 1 of connector J2 (PVIN) and negative terminal of supply to pin 2 of connector J2 for ground using 16 AWG wire or larger. [Note: For more precise measurements, eliminating the IR voltage drop in the input cables is achieved by using a power supply source with sensing ports and connecting between TP4 to PVIN and TP18 to GND.]
3. DC electronic load
   1. Connect positive DC input of e-load to pin 2 of connector J4 (VOUT) using 16 AWG wire.
   2. Connect negative DC input of e-load to pin 1 of connector J4 (VOUT) using 16 AWG wire.
   3. Connect voltage monitoring sensing ports of e-load across test points TP15 (VOUT1) and TP20 (GND). A voltage meter can be used to monitor this voltage also.
4. Oscilloscope
   1. CH1 - Connect voltage scope probe to scope probe test point J6 (PH1) to monitor the phase node. DC coupled, Full BW, 2 V/div, Rising Edge Trigger at 0.5 V.
   2. CH2 - Connect voltage scope probe to scope probe test point J13 (PH2) to monitor the phase node. DC coupled, Full BW, 2 V/div, Rising Edge Trigger at 0.5 V.
   3. CH3 - Connect voltage scope probe to scope probe test point J12 (PH3) to monitor the phase node. DC coupled, Full BW, 2 V/div, Rising Edge Trigger at 0.5 V.
   4. CH4 - Connect voltage scope probe to scope probe test point J10 (PH4) to monitor the phase node. DC coupled, Full BW, 2 V/div, Rising Edge Trigger at 0.5 V.
