General Description FeaturesMEXX1C Series is a PFM Step-up DC/DC converterIC with low supply current by CMOS process. Highfrequency noise that occurs during switching isreduced by using advanced circuit designed, outputvoltage is programmable in 0.1V steps between2.0~7.0V and maximum frequency is 100KHz (TYP.).A low ripple, high efficiency step-up DC/DC convertercan be constructed of MEXX1C with only threeexternal components. Also available is a CE(chipenable) function that reduce power dissipationDuring shut-down mode. MEXX1C is suitable for usewith battery-powered instruments with low noise andlow supply current. l Low input current:6μA(TYP.)l Low ripple and low noisel Operating voltage range:0.9V~6.5Vl Output voltage range:2.0V~7.0V(step 0.1V)l Output voltage accuracy:±2.5%；l Output Current: if VIN=3.0V and VOUT=3.3V,thenIOUT=250mAl Low start voltage:<0.9V(at IOUT=1mA)l Maximum oscillator frequency:100KHz(TYP.)l High Efficiency:85%(Type)l Package:SOT23、SOT89、TO92
