TEST SET-UP FOR GRAPHS
(1)
All measurements were taken with a 1-
μF CI (unless otherwise noted.)
(2)
A 33-
μH inductor was placed in series with the load resistor to emulate a small speaker for efficiency measurements.
(3)
The 30-kHz low-pass filter is required, even if the analyzer has an internal low-pass filter. An RC low-pass filter (1 k
4.7 nF) is used on each output for the data sheet graphs.
