XC6385 Datasheet | Torex Semiconductor

- NPager Use : Low Noise NDuty Ratio : 75% NCMOS Structure : Small Supply Current NOperating Voltage Range : 0.9~10.0V NOutput Voltage Range : 2.0~7.0V NOutput Voltage Accuracy : ±2.5% GPagers GPalmtops GCameras, Video cameras GVarious portable products 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 mon 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 100k Hz (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...
