Output voltage vs. load current at IO > max IO , TP1 = +25°C.
Start-up
Output Load Transient Response
Start-up enabled by connecting VI at:
TP1 = +25°C, VI = 53 V,
IO = 25 A resistive load.
Top trace: output voltage (5 V/div).
Bottom trace: input voltage (50 V/div).
Time scale: (10 mS/div)
Output voltage response to load current step-
change (6.25-18.75 -6.25 A) at:
TP1 =+25°C, VI = 53 V.
Top trace: Output voltage (500 mV/div).
Bottom trace: load current (10 A/div).
Time scale: (0.5 mS/div)
