All parameters are measured according to the conditions described in Specifications. Figure 31 shows the setup used for the typical characteristics of the test device.
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.
