When the electronic load is turned on at 1.5A load current,
SM3320-RF-EV will operate in Panel Mode for at least 128
seconds. After this period, the MPPT mode is then entered.
During MPPT, the output voltage is at 38V with an input volt-
age of 30V. Once the shutdown signal is received by the
receiver, one of the Nordic GPIO output will pull the reset line
down causing the SM3320-RF-EV to stop switching and re-
sulting the output voltage will go down
(Figure
7).
