ELECTRICAL CHARACTERISTICS

XCL101Axx1BR-G/XCL101Axx1ER-G

Unless otherwise stated, VBAT= VCE= 1.5V

(*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) LX SW “Pch” ON resistance =（VLX-VOUTpin measurement voltage） / 200mA

(*4) LX SW “Nch” ONresistance measurement method is shown in the measurement circuit diagram.
