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 d...
