■General Description  
■Features  
The XC6383 series is a group of PFM controlled step-up DC/DC  
converters. Unlike conventional PFMs, the XC6383 automatically  
switches duty ratio (55% / 75%) when it senses changes in load and can  
support both large and small currents.  
Operating (start-up) voltage range  
: 0.9V~10V  
Output voltage range : 2.0V~7.0V in 0.1V increments  
Highly accurate  
Maximum oscillator frequency  
: 100kHz ( 15%)  
: Set-up voltage 2.5%  
The XC6383 series employs CMOS process and laser trimming  
technologies so as to attain low power and high accuracy.  
Maximum oscillator frequency is trimmed to 100kHz (accuracy: 15%).  
Every built-in switching transistor type enables a step-up circuit to be  
configured using only three external components ; a coil, a diode, and a  
capacitor.  
Variable Duty Ratio : 55% / 75% ( 5%)  
Both switching transistor built-in and external types are  
available  
Five-lead packaged units offer either Chip Enable or  
independent VOUT pin option.  
External transistor versions are available to accommodate high output  
current applications.  
Small package  
: SOT-23, 25 mini-mold (3-pin, 5-pin)  
SOT-89, 89-5 mini-power mold  
(3-pin, 5-pin)  
Both built-in and external transistor types include 5-pin and 3-pin  
packages, which are provided with either a CE (chip enable) function that  
reduces power comsumption during shut-down mode, or a VDD pin  
function (separated power and voltage detect pins).  
SOT-23, SOT-25, and SOT-89-5 ultra mini-mold packages.
