Overview

Preliminary RT9261/A VFM Step-up DC/DC Converter General Description The RT9261 Series are VFM Step-up DC/DC ICs with ultra low supply current by CMOS process and suitable for use with battery-powered instruments.
The RT9261 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 of this RT9261 IC with only three external components.
The RT9261A IC provides with a drive pin (EXT) for an external transistor, so that a power transistor can be externally applied.
Therefore, t...
