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 of XC6381 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
