(3) Connect the DC electronic load or 48V battery to one or more of the BAT48 connectors. See
ISL78226 connections and
phases together and all BAT48 PGNDs together. For high power evaluations, Renesas recommends
connecting the 48V load or battery to all six phases for distribution of power across the board.
(4) Connect a 12V supply or battery to one or more of the BAT12 connectors. See
connections and
and all BAT12 PGNDs together. For high power evaluations, Renesas recommends connecting the 12V
supply or battery to all six phases for distribution of power across the board.
(5) Connect a 12V supply to the VIN and VIN_FLY with its ground connected to FLYGND. Disconnect the
5V supply from BAT12_IN if it was previously connected. See
Figure 56
for ISL78224 connections. The evaluation board has a diode to prevent the reverse current
flowing from the BAT12 supply to the 5V supply so the 5V supply can be safely disconnected. A normal
application circuit has a 12V battery for precharge and the BAT12_IN voltage is not required.
(6) Connect probes as shown in
through the software and turning off all supplies before making connections to the board.
(7) Turn on the 12V supplies, 5V supplies, and the 48V supply (no particular power supply sequence).
