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 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)
