■ELECTRICAL CHARACTERISTICS

XC6367A333MR, XC6368A333MR

Conditions: Unless otherwise stated, connect VDD to VOUT; VIN=setting output voltage x 0.6, IOUT=130mA

NOTE:

* 1: When taking V

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

Oscillation will occur with a value of V

DD = 0.8V or more, but with a value of VDD = 2.0V or more,

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).

VOUT=3.3V, FOSC=300kHz, Ta=25℃

*Voltage is all ground standardized.
