TYP

Unless otherwise specified, connect VDD to VOUT ; VIN=set-up output voltage x 0.6, IOUT=200mA

Measuring conditions:

When taking VDD from another power source please ensure that VDD = 2.0V or more.

Oscillation will occur with a value of VDD = 0.8V or more, but with a value of VDD = 2.0V or more,

output voltage and oscillation frequency will be stable.

Note 1:

EFFI = {[(output voltage) x (output current)]

÷ [(input voltage) x (input current)} x 100

Note 2:

Applies to the XC6368 series only (duty ratio when control changes to PFM).

Note 3:

There are no products within the XC6367E, XC6368E series range which have a set-up

voltage of less than 2.0V.

Note 4:

XC6367C, XC6368C series
