The XC6385 series are a group of PFM (frequency) controlled step-up
DC/DC converters.
The XC6385 series employs CMOS process and laser trimming
technologies to attain low power and high accuracy.
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.)
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.
SOT-89-5 and SOT-23/25 small packages.
For typical application circuit and electrical characteristics of XC6385 series, please refer to that of XC6382 series.
For more detail, please contact Torex sales offices or sales person.
