Start-up
Output Load Transient Response
Start-up enabled by connecting VI at:
TP1, TP3 = +25°C, VI = 53 V,
Top trace: output voltage (5 V/div.).
Bottom trace: input voltage (50 V/div.).
Time scale: (10 ms/div.).
Output voltage response to load current Top trace: output voltage (0.5 V/div.).
step-change (17.5-52.5-17.5 A) at:
Bottom trace: output current (20 A/div.).
Time scale: (0.5 ms/div.).
TP1, TP3 =+25°C, VI = 53 V, CO = 3.9 mF
