Start-up
Shut-down
Start-up enabled by connecting VI at:
Tref = +25°C, VI = 53 V,
O = 40 A resistive load.
Top trace: output voltage (1 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (50 ms/div.).
Shut-down enabled by disconnecting VI at:
Tref = +25°C, VI = 53 V,
O =40 A resistive load.
Top trace: output voltage (2 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (0.5 ms/div.).
