FEATURES  
GENERAL DESCRIPTION  
The XC6367/68 series are multi-functional step-up DC/DC  
converter controllers with built-in high speed, low ON resistance  
drivers.  
Input Voltage Range : 0.9V ~ 10V  
Operating Voltage Range : 2.0V ~ 10V  
Output voltage Range : 1.5V ~ 6.5V programmable in  
Large output currents are possible using an externally  
connected transistor, coil, diode and capacitor.  
Output voltage is selectable in 100mV 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 XC6367/68A, B, and C series is internally set  
to 10msec 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.  
100mV increments (±2.5%)  
Oscillation Frequency : 300kHz, 100kHz (  
±15%)
