XC9272 Series
ETR05057-001
Ultra Low Quiescent Current Synchronous Step-Down PFM DC/DC Converter for Low Output Voltage
■GENERAL 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 needed as external parts to make a step down DC/DC circ...
