Start-up
Shut-down
Start-up enabled by connecting VI at:
TP1 = +25°C, VI = 53 V
IO = 21.5 A resistive load.
Top trace: output voltage 10 V/div.
Bottom trace: input voltage 20 V/div.
Time scale: 5 ms/div.
Shut-down enabled by disconnecting VI at:
TP1 = +25°C, VI = 53 V,
IO = 21.5 A
Top trace: output voltage 10 V/div.
Bottom trace: input voltage 20 V/div.
Time scale: 50 ms/div.
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple at:
TP1 = +25°C, VI = 53 V
IO = 21.5 A resistive load.
Trace: output voltage 100 mV/div.

Trace: output voltage 0.5 V/div.
Time scale: 0.2 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:
