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.
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 CE to VOUT, VIN=VOUT ✕ 0.6, IOUT=30mA. See Typical Application Circuits, Fig.3.
Note: 1. The Schottky diode (SD) must be type MA735, with reverse current (IR) <1.0µA 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)".
