Description
XC9147/XC9148 series are synchronous step-up DC/DC converters with a 0.17Ω Nch driver FET and a 0.2Ω synchronous
Pch switching FET built-in.The series are able to start operation from an input voltage of 0.9V, suitable for equipment using single Alkaline battery or Nickel
metal hydride battery.The output voltage can be set from 1.8V to 5.5V in steps of 0.1V.During the devices enter stand-by mode, A/D/G/J types prevent the application malfunction by CL Discharge function which can quickl
