5.4 Transient Response
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 converters had 5x22µF
ceramic capacitors and a 220µF tantalum capacitor
connected across the output pins. The speed of the
transient response was optimized by selecting
appropriate CCA settings.
