All limits at temperature extremes are guaranteed via correlation using standard statistical quality control (SQC).
Transconductance and voltage gain measurements refer to the internal amplifier without the voltage divider. To calculate the transconductance and gain of the fixed
voltage parts, divide the values shown by FB/1.20.
The switching frequency is reduced when the feedback pin is lower than 0.8 × FB.
See Figure 24 for typical application circuit.
Switch current limit is measured with no diode, no inductor, and no output capacitor.
Minimum input voltage is not measured directly, but is guaranteed by other tests. The actual minimum input voltage needed to keep the output in regulation
depends on output voltage and load current.
