Overview
Preliminary RT9261B VFM Step-up DC/DC Converter General Description 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.
