Dissipated power vs. load current and input voltage at
TPcb=+25 °C
Start-up at Io=25A resistive load at TPcb=+25 °C,
Vin=53 V. Start enabled by connecting Vin.
Trace 1: input voltage (20 V/div.).
Trace 2: output voltage (1 V/div.).
Time scale: 50 ms/div.
Turn-off at Io=25A resistive load at TPcb=+25 °C,
Vin=53 V. Turn-off enabled by disconnecting Vin.
Trace: output voltage (100 mV/div.).
Time scale: 1 ms/div.
