RT9261B-50PX - Brand New RICHTEK IC Chips
-
Description
The RT9261B-50PX is a VFM Step-up DC/DC converter IC from the RT9261B Series. It is designed with ultra low supply current by CMOS process, making it suitable for use with battery-powered instruments. The IC features 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. With only three external components, a low ripple and high efficiency step-up DC/DC converter can be constructed using the RT9261B-50PX.
