The following steps are used for the test setup:
- Flash the PMP41081 code into the F280039C control card, and switch all S2 to position '1'
- Insert the F280039C control card and the auxiliary power board into the base board
- Connect the input DC source and output electronic load
- Consider using an extra cooling fan to minimize
the temperature of the power board
- Switch the 'S101' to the 'ON' side, on the base board
- Power on the DC source with 400 V, the 12-V output automatically starts up within 20 s
Figure 1-1 illustrates the test setup.
