Follow the instructions to verify the output short-circuit protection feature of the device:

1. Set up the oscilloscope as listed in Table 4-10.
   Table 4-10 TPS2640EVM Output Short-Circuit Protection Test

   Oscilloscope Setting	CH1 Probe Points	CH2 Probe Points
   Channel 1 = 10 V / div	VOUT1 (TP3)	VOUT2 (TP12)
   Channel 2 = 10 V / div	VIN1 (TP2)	VIN2 (TP11)
   Channel 3 = 20 V / div	FLTb1 (TP1)	FLTb2 (TP10)
   Channel 4 = 2 A / div	Input current into T1 +Ve wire	Input current into T3 +Ve wire
   Trigger source = Channel 1
   Trigger level = 12 V ±1 V
   Trigger polarity = Falling
   Trigger mode = Single
   Time base	2 ms / div

2. Set the load resistance to 16 Ω ±1 Ω and the power supply voltage to 24 V.
3. Enable the load and the power supply.
4. Use either wire or FET to short the output to ground and verify the output short-circuit response waveform as shown in Figure 4-7.
