ELECTRICAL CHARACTERISTICS

XC6367A333MR, XC6368A333MR

NOTE:

output voltage and oscillation frequency will be stable.

* 2: EFFI = {[(output voltage) x (output current)]÷[(input voltage) x (input current)] x 100

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

*Voltage is all ground standardized.
