The pictures below show the deviation of the output
voltage in response to the 50%-75%-50% step load
at 1.0A/µs. In all tests the POL converter had a total
of 380µF ceramic and tantalum capacitors connected
across the output pins. The speed of the transient
response was varied by selecting different CCA
settings.
