ME2101 Overview
ME2101 Series Ver 02 ME2101 Series Step-up DC-DC Converter ME2101 Series is a PWM 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 2.0~5.0V and maximum frequency is 100KHz(Typ.). A low ripple, high efficiency step-up DC/DC converter can be...
