board layout, the rated thermal package thermal resistance and other
environmental factors. The junction temperature (TJ) is calculated from
the ambient temperature (TA) and power dissipation (PD) according to
the formula: TJ = TA + (PD θJA°C/W), where θJA is the package thermal
impedance.
Note 3: Specification is guaranteed by design and not 100% tested in
production.
Note 4: Current measurements are made when the output is not switching.
Note 5: Failure to solder the exposed backside of the QFN package to the
PC board ground plane will result in a thermal resistance much higher
than 37°C/W.
Note 6: The Absolute Maximum Rating is a DC rating. Under certain
conditions in the applications shown, the peak AC voltage on the C2A and
C2B pins may exceed ±8V. This behavior is normal and acceptable because
the current into the pin is limited by the impedance of the coupling
capacitor.
