Start-up
Shut-down
Start-up enabled by connecting VI at:
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:
ref = +25 °C, VI = 53 V,
IO = 20 A resistive load.
Top trace: output voltage (5 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (0.1 ms/div.).
Tref = +25 °C, VI = 53 V,
T
IO = 20 A resistive load.
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple at:
Trace: output voltage (50 mV/div).
Time scale: (2 µs/div.).
Output voltage response to load current step- Top trace: output voltage (0.5 V/div.).
Tref = +25 °C, VI = 53 V,
change (10-15-10 A) at:
Tref =+25 °C, VI = 53 V, Cout = 220 μF.
Bottom trace: load current (5 A/div).
Time scale: (0.1 ms/div.).
IO = 20 A resistive load.
