s General Description
The XC6382 series is a group of PFM controlled step-up DC/DC converters. The XC6382 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 consumption during shut-down mode, or a VDD pin function (separating 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%) Duty ratio: 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 VDD to VOUT, VIN=VOUT 0.6, IOUT=10mA. See Typical Application Circuits, Fig.5. Note: 1. The Schottky diode (SD) must be type MA735, with reverse current (IR) <1.0A at reverse voltage (VR)=10.0V 2. "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)". When the VDD and VOUT pins are independently used, the voitage range at the VDD pin should be 2.2V to 10V. The IC operates from VDD=0.8V. However, output voltage and oscillator frequency are properly stabilized when VDD=2.2V or higher.
