■General Description

The XC6381 series is a group of PFM controlled step-up DC/DC

converters.

■Features

Operating (start-up) voltage range

: 0.9V~10V

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: 15ꢀ%.

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.

Output voltage range : 2.0V~7.0V in 0.1V increments

Highly accurate

Maximum oscillator frequency

: 155kHz ( 15ꢀ%

: 58ꢀ ( 5ꢀ%

: Set-up voltage 2.5ꢀ

Duty Ratio

Both built-in switching transistor and external types are

available

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 (separated power and voltage detect pins%.

Five-lead packaged units offer either Chip Enable or

independent V^OUTpin option.

Small package

: SOT-23, 25 mini-mold (3-pin, 5-pin%

SOT-89, 89-5 mini-power mold

(3-pin, 5-pin%

SOT-23, SOT-25, and SOT-89-5 super mini-mold packages.
