Start-up
Shut-down
Start-up enabled by connecting VI at:
Tp1 = +25°C, VI = 53 V,
IO = 50 A resistive load.
Top trace: output voltage (0.5 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (5 ms/div.).
Shut-down enabled by disconnecting VI at:
Tp1 = +25°C, VI = 53 V,
IO = 50 A resistive load.
Top trace: output voltage (0.5 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (0.1 ms/div.).

Output Voltage Adjust (see operating information)
Passive adjust
The resistor value for an adjusted output voltage is calculated by
using the following equations:
