TEST SET-UP FOR GRAPHS

(1)

CI was shorted for any common-mode input voltage measurement. All other 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

(100

Ω, 47-nF) is used on each output for the data sheet graphs.

(4)

L = 4.7

μH is used for the boost converter unless otherwise noted.
