The RT9261B Series are VFM Step-up DC/DC converter
ICs with ultra low supply current by CMOS process and
suitable for use with battery-powered instruments.
The RT9261B IC consists of an oscillator, a VFM control
circuit, a driver transistor (LX switch), a reference voltage
unit, an error amplifier, resistors for voltage detection, and
a LX switch protection circuit. A low ripple and high efficiency
step-up DC/DC converter can be constructed with the
RT9261B IC and only three external components.
The EN pin enables the circuit to set the standby supply
current at a maximum of 0.5uA.
