s General Description
The XC6383 Series is a group of PFM controlled step-up DC/DC converters. Unlike conventional PFMs, the XC6383 automatically switches duty ratio (55%/75%) when it senses changes in load and can support both large and small currents. The XC6383 series employs CMOS process and laser trimming technologies so as to attain low power and high accuracy. Max. oscillator frequency is trimmed to 100kHz (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 comsumption 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.
s Features
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: 100kHz (15%) Variable Duty Ratio: 55%/75% (5%) Both switching transistor built-in 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)

Measuring conditions: Unless otherwise specified, connect CE to VOUT, VIN=VOUT 0.6, IOUT=30mA. See Typical Application Circuits, Fig.4. Note: 1."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 VIN source is represented by "No-Load Input Current (IIN)".
