Test Setup

To perform an evaluation on the SM72445 evaluation board, it is suggested that the user connect the

input to a SAS (Solar Array Simulator) and the output to a load bank, preferably in Current mode (Voltage

mode sometimes causes regulation issues with some electronic load when used with the evaluation

board). The following sequence can be used to verify the operation of the board:

• Connect S.A.S. to input.

• Connect Electronic load to output.

• Turn on SAS Verify proper startup pattern (see Figure 4).

• Set Electronic load to 2A and turn on Electronic load.

• Wait two minutes and verify that SAS is operating at Maximum Power Point. If output voltage is

close to 40V, increase Electronic load current.

• Vary Electronic load current and verify that the SAS is operating at Maximum Power Point in

step-up (lower load current) and step-down (higher load current) operation.
