ME2186

Description£º
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. Also available is a CE (chip enable) function that reduce power dissipation during shut-down mode. ME2186Xxx is suitable for use with battery-powered instruments with low noise and low supply current.
