■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%.
