TEST SET-UP FOR GRAPHS
(1)
CI was shorted for any common-mode input voltage measurement. All other measurements were taken with a 1-F CI
(unless otherwise noted).
(2)
A 33-
H 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.
(4)
L = 6.2
H is used for the boost converter unless otherwise noted.
