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 VDD 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 VOUT pin option.
Small package
: SOT-23, 25 mini-mold (3-pin, 5-pin)
SOT-89, 89-5 mini-power mold
(3-pin, 5-pin)
