ME2186A50PG

Description

ME2186 Series is a Synchronous 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 1.8~6.0V.A low ripple, high efficiency step-up DC/DC converter can be 

constructed of ME2186Xxx with only three external components. ME2186Xxx is suitable for use with 

battery-powered instruments with low noise and low supply current..
