XC6367/XC6368 Series
PWM Controlled, PWM/PFM Switchable Step-up DC/DC Controllers
ETR0401_005
☆GreenOperation-Compatible
■GENERAL DESCRIPTION
The XC6367/XC6368 series are multi-functional step-up DC/DC controllers which provide high efficiency outputs by using an
externally connected transistor, coil, diode and capacitor.
Output voltage is selectable in 0.1V increments within a range of 1.5V ~ 6.5V (±2.5%). For output voltages outside this
range, we recommend FB version, which has a 1.0V internal reference voltage. Using the FB version, the required output
voltage can be set-up using 2 external resistors.
With a 300kHz oscillation frequency, the size of the external components can be reduced.
Control switches from PWM to PFM during light loads with the XC6368 (PWM/PFM switchable) and the series is highly
efficient from light loads to large output currents.
Soft start time of XC6367/ XC6368A, B, and E series is internally set to 10ms and XC6367/68C, D, and F series regulate
soft-start time by connecting resistors and capacitors externally.
During stand-by (CE pin "Low"), supply current is reduced to less than 0.5μA.

Conditions: Unless otherwise stated, connect VDD to VOUT; VIN=setting output voltage x 0.6, IOUT=130mA
NOTE:
* 1: 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.
* 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).
