XC9272 Product details

Description

☆GreenOperation compatible XC9272 series are Ultra Low Quiescent Current synchronous-rectification for Low Output Voltage type PFM step down DC/DC converters with a built-in 0.4Ω (TYP.) Pch driver and 0.4Ω (TYP.) Nch synchronous switching transistor, designed to allow the use of ceramic capacitor.PFM control enables a low quiescent current, making these products ideal for battery operated devices that require high efficiency and long battery life.Only inductor, CIN and CL capacitors are
