DC/DC升压IC

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 \60 pin function (separated power supply and voltage detect pins) for fly-back circuits.

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