■General Description

The XC6385 series are a group of PFM (frequency) controlled step-up

DC/DC converters.

■Features

Low noise

Operating voltage range : 0.9V~10V

The XC6385 series employs CMOS process and laser trimming

technologies to attain low power and high accuracy.

Output voltage range

: 2.0V~7.0V (programmable in 0.1V

steps)

A common problem among pagers is one of noise, but with the XC6385,

high frequency noise that occurs during switching is reduced.

Output voltage is selectable in 0.1V steps within 2.0V ~ 7.0V and

maximum frequency is 100kHz (Typ.)

Output voltage accuracy: 2.5%

Maximum oscillator frequency

: 100kHz ( 15%)

Built-in switching transistor

With a built-in switching transistor, a step-up circuit can be configured

using a coil, diode and capacitor connected externally.

Also available is a CE (chip enable) function that reduces power

consumption during shut-down mode, and an independent VDD pin

function (separated power supply and voltage detect pins) for fly-back

circuits.

CE function and/or separated V^DD/VOUT types selectable with

5 pin packages

Small package

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

SOT-89/89-5 mini-power mold

(3 pin, 5 pin)

SOT-89-5 and SOT-23/25 small packages.
