■General Description  
The XC6382 series is a group of PFM controlled step-up DC/DC  
converters.  
■Features  
Operating (start-up) voltage range  
: 0.9V~10V  
The XC6382 series employs CMOS process and laser trimming  
technologies so as to attain low power and high accuracy.  
Max. oscillator frequency is trimmed to 100kHz (accuracy: 1ꢀ5%  
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.  
Output voltage range : 2.0V~7.0V in 0.1V increments  
Highly accurate  
Maximum oscillator frequency  
: 100kHz ( 1ꢀ5%  
: 7ꢀ5( ꢀ5%  
: Set-up voltage 2.ꢀ5  
Duty ratio  
Both switching transistor built-in and external types are  
available.  
External transistor versions are available to accommodate high output  
current applications.  
Five-lead packaged units offer either Chip Enable or  
independent VOUT pin option.  
Both built-in and external transistor types include ꢀ-pin and 3-pin  
packages, which are provided with either a CE (chip enable% function that  
reduces power consumption during shut-down mode, or a VDD pin  
function (separating power and voltage detect pins%.  
Small package  
: SOT-23, 2ꢀ mini-mold (3-pin, ꢀ-pin%  
SOT-89, 89-ꢀ mini-power mold  
(3-pin, ꢀ-pin%  
SOT-23, SOT-2ꢀ and SOT-89-ꢀ super mini-mold packages.
