ME2100B50PG

ME2100 Series Ver 07 ME2100 Series Step-up DC-DC Converter ME2100 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 ME2100Xxx with only three external components. Also available is a CE(chip enable) function that reduce power dissipation During shut-down mode. ME2100Xxx 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)； • Maximum oscillator frequency： 100KHz(Typ.)； • High Efficiency：85%(Type)； • PACKAGE ： SOT23-3 ， SOT23-5 ， SOT89-3 ， SOT89-5 Selection Guide ME 21 00 A xx Applications X Power source for battery-powered equipment； • Power source for wireless mouse, wireless keyboard, toys, cameras, camcorders, VCRs, PDAs, and hand-held communication equipment； • Power source for appliances which require higher cell voltage than that of batteries used in the appliances。 • Package P–SOT89 M–SOT23 Feature Code 27–2.7V 30–3.0V 33–3.3 50–5.0V …...
