升压DC-DC ME2110 微盟一级代理

general description

me2110 series is a pfm step-up dc/dc converter ic with lowsupply current by cmos process. high frequency noise that occursduring switching is reduced by using advanced circuit designed,output voltage is programmable in 0.1v steps between 1.8~6.0v.a lowripple, high efficiency step-up dc/dc converter can be constructedof me2110xxx with
only three external components. also available is a ce (chipenable) function that reduce power dissipation during shut-downmode. me2110xxx is suitable for use with battery-poweredinstruments with low noise and low supply current.
