NDuty 58% NCMOS Low Power Consumption NOperating Voltage NOutput Voltage Range : 0.9V~10.0V : 2.0V~7.0V GCellular phones, pagers GPalmtops GCameras, video recorders GPortable equipment NOutput Voltage Accuracy : ±2.5% 4 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.
