产品详细介绍
general description
me2108 series is a pfm
step-up dc/dc converter ic with low supply current by cmos process.
high frequency noise that occurs during switching is reduced by
using advanced circuit designed, outputvoltage is programmable in
0.1v steps between 2.0~7.0v and maximum frequency is 180khz(typ.).
a low ripple, high efficiency step-up dc/dc converter can be
constructed of me2108xxx with only three external components. also
available is a ce(chip enable) function that reduce power
dissipation during shut-down mode. me2108xxx is suitable for use
with battery-powered instruments with low noise and low supply
current.
