Start-up
Shut-down
Start-up enabled by connecting VI at:
Tref = +25°C, VI = 53 V,
IO = 7.5 A resistive load.
Top trace: output voltage 5 V/div..
Bottom trace: input voltage 50 V/div..
Time scale: 5 ms/div..
Shut-down enabled by disconnecting VI at:
Tref = +25°C, VI = 53 V,
Io =7.5A resistive load.
Top trace: output voltage 5 V/div.
Bottom trace: input voltage 50 V/div..
Time scale: 0.5 ms/div..
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple at:
Tref = +25°C, VI = 53 V,
Io = 7.5 A resistive load.
Trace: output voltage 20 mV/div.
Time scale: 2 s/div.
Output voltage response to load current step-
change 1.875A-5.625A-1.875A at:
Tref =+25°C, VI = 53 V.
Top trace: output voltage 500 mV/div.
Bottom trace: load current 5 A/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:
