The RT9261B Series are VFM Step-up DC/DC converterICs with ultra low supply current by CMOS process andsuitable for use with battery-powered instruments.The RT9261B IC consists of an oscillator, a VFM controlcircuit, a driver transistor (LX switch), a reference voltageunit, an error amplifier, resistors for voltage detecTIon, anda LX switch protecTIon circuit. A low ripple and high efficiencystep-up DC/DC converter can be constructed with theRT9261B IC and only three external components.The EN pin enables the circuit to set the standby supplycurrent at a maximum of 0.5uA.
