ME2188 High Efficiency ,synchronous PFM step-up DC-DC converter General

Description

ME2188 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 1.8V~5.0V and maximum frequency is 350KHz(TYP.). A low ripple, high efficiency step-up DC/DC converter can be constructed of ME2188Xxx with only two external components. with low noise and low supply current. ME2188Xxx is suitable for use with battery-powered instruments
