Description
The RT9261A-50CB is a VFM Step-up DC/DC IC suitable for use with battery-powered instruments. It 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. This IC allows for the construction of a low ripple and high efficiency step-up DC/DC converter with minimal external components.
