(*1)

VOUT(T)=Nominal Output Voltage

(*2)

VOUT(E)=Effective Output Voltage

The actual output voltage value VOUT(E) is the PFM comparator threshold voltage in the IC.

Therefore, the DC/DC circuit output voltage, including the peripheral components, 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.

EFFI=[{ (Output Voltage)×(Output Current)] / [(Input Voltage)×(Input Current)}]×100

(*5) LX SW “Pch” ON resistance = (VIN – VLX pin measurement voltage) / 100mA
