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 V DD pin function (separated power supply and voltage detect pins) for fly-back circuits. SOT-89-5 and SOT-23/25 small packages. ˙&MFDUSJDBM$IBSBDUFSJTUJDT For typical application circuit and electrical characteristics of XC6385 series, please refer to that of XC6382 series.
