Regulation (PCU)
a.
Voltage Regulation: ±1%.
b.
Load Regulation: ±0.5%.
c.
Line Regulation: ±0.1%.
d.
Overshoot at Startup: ±1%.
e.
Dynamic Response (at rated input and output voltage values):
•Response time is 200 µs, and the overshoot is 5% for load changes at 50%-25%-50% and 50%-
•Response time is 200 µs, and the overshoot is 5% for load changes at 50%-25%-50% and 50%-
75%-50%.
•Overshoot or undershoot is 5% and within ±1% of the regulation band, 4 ms at 50 µs for load
changes at 10%-90% and 90%-10%.
Filtering
Typical readings were taken at nominal input voltage, nominal output voltage, 50% load, and 25
degrees C ambient.
