Output voltage vs. load current at Tref = +25°C
Output voltage vs. load current at IO > max IO , Tref = +25°C
Start-up
Shut-down
Start-up enabled by connecting VI at:
Tref = +25°C, VI = 53 V,
IO = 38 A resistive load.
Top trace: output voltage (2 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (20 ms/div.).
Shut-down enabled by disconnecting VI at:
Tref = +25°C, VI = 53 V,
IO =38 A resistive load.
Top trace: output voltage (2 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (0.2 ms/div.).
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple at:
Tref = +25°C, VI = 53 V,
IO = 38 A resistive load.
Trace: output voltage (20 mV/div.).
Time scale: (2 µs/div.).
Output voltage response to load current step- Top trace: output voltage (0.2 V/div.).
change (9.5 – 28.5 – 9.5 A) at:
Bottom trace: output current (20 A/div.).
Time scale: (0.5 ms/div.).
Tref =+25°C, VI = 53 V. Co = 3.8 mF
