XA2100

XA2100 XA2100 Series Step-up DC-DC Converter XA2100 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 2.0~7.0V and maximum frequency is 100KHz(Typ.). A low ripple, high efficiency step-up DC/DC converter can be constructed of XA2100X xx with only three external components. Also available is a CE(chip enable) function that reduce power dissipation During shut-down mode. XA2100Xxx is suitable for use with battery-powered instruments with low noise and low supply current. Features Low input current：6µA(Type)； Low ripple and low noise； Operating voltage range：0.9V~6.5V； Output voltage range：2.0V~7.0V(step 0.1V)； Output voltage accuracy：±2.5%； Output Current：if Vin=3.0V and Vout=3.3V，then Iout=300mA； Low start voltage：≤0.9V(at Iout=1mA...
