Bottom trace: input voltage (50 V/div.).
Time scale: (5 ms/div.).
Shut-down enabled by disconnecting VI at:
ref = +25 °C, VI = 53 V,
O = 40 A resistive load.
Cout = 1 mF.
Top trace: output voltage (2 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (1 ms/div.).
Tref = +25 °C, VI = 53 V,
