Unless otherwise stated, VIN=VCE=5.0V
(*1) VOUT(T)=Nominal Out put Voltage
(*2) VOUT(E)=Effective Output Voltage
The actual output voltage value VOUT(E) is the PFM comparator threshold voltage in the IC.
Therefore, t he DC/DC circuit output voltage, incl udi ng the peripheral c omponents, is boosted by the ripple voltage average value.
Please refer to the characteristic example.
(*3) Not applicable to the products with VOUT(T) < 2.15V since it is out of operational volatge range.
(*4) EFFI=[{ (Output Voltage)×(Out put Current)] / [(Input Voltage)×(Input Current)}]×100
(*5) L X SW “Pch” ON resistance = (VIN – VLX pin measurement voltage) / 100mA
