The XC6381 series is a group of PFM controlled step-up DC/DC
converters.
The XC6381 series employs CMOS process and laser trimming
technologies so as to attain low power and high accuracy.
Max. oscillator frequency is trimmed to 155kHz (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. External transistor versions are available to accommodate
high output current applications.
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 consumption during shut-down mode, or a V
DD
pin
function (separated power and voltage detect pins).
SOT-23, SOT-25, and SOT-89-5 super mini-mold packages.
Operating (start-up) voltage range
: 0.9V~10V
Output voltage range : 2.0V~7.0V in 0.1V increments
Highly accurate
: Set-up voltage 2.5%
Maximum oscillator frequency
: 155kHz (15%)
Duty Ratio
: 58% (5%)
Both built-in switching transistor and external types are
available
Five-lead packaged units offer either Chip Enable or
independent V
OUT
pin option.

1. The Schottky diode (SD) must be type MA735, with reverse current (I
R
)<1.0
A at reverse voltage (V
R
)=10.0V.
2. "Supply Current 1" is the supply current while the oscillator is continuously oscillating. In actual operation the oscillator periodically operates
which results in less average power consumption. The current actually provided by an external V
IN
source is represented by "No-Load Input
Current (I
IN
)".
*
When the V
DD
and V
OUT
pins are independently used, the voltage range at the V
DD
pin should be 2.2V to 10V.
The IC operates from V
DD
=0.8V. However, output voltage and oscillator frequency are properly stabilized when V
DD
=2.2V or higher.
