TPS2350 48-V Hot Swap/Supply Selector Evaluation Module
3.2
Verifying the EVM Operation
The following procedure steps may be used to verify functional operation of the EVM after receipt.
3.2.1
Equipment Setup
On the EVM, place the POWER and ENABLE switches in the OFF position.
Set the DIP switches 1 through 4 of switch SW1 to the ON position.
Turn on power supply number 1 (PS No. 1) and adjust the output for about 48 V. Turn on power supply number
2 (PS No. 2) and adjust the output for about 44 V. Verify the current limit of supplies 1 and 2 is set to allow sourcing
of at least 3 A. Turn off the supplies
Turn on power supply number 3 (PS No. 3), and adjust the output to about 5 V. Turn off the power supply.
Connect the EVM and test equipment as shown in Figure 4.

Figure 4. TPS2350 48-V Supply Selector EVM Equipment Setup
On the oscilloscope, set the channel amplifiers to the following scales:
CH1: 2 V/div
CH2: 2 V/div
CH3: 5 V/div
CH4: 20 V/div
For easier correlation to the information in this document, the scope trace baselines can be positioned as shown
in Figure 5.
Set the scope to trigger on the rising edge of channel 1, at about a 1-V level. Set the scope timebase to 10 ms,
and the trigger mode to NORMAL.
