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, output
voltage is programmable in 0.1V steps between
2.0~7.0V and m aximum frequency is 180KHz(T YP .).
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 u se with battery-powered instruments
with low noise and low supply current.
