Produktinformationen "NCP81172MNTXG"


2-Phase Synchronous Buck Controller with Integrated Gate Drivers and PWM VID Interface


The NCP81172, a general−purpose two−phase synchronous buck controller, integrates gate drivers and PWM VID interface in a QFN−24 package and provides a compact−footprint power management solution for new generation computing processors. It receives power save command (PSI) from processors and operates in 1−phase diode emulation mode to obtain high efficiency in light−load condition. Operating in high switching frequency up to 800 kHz allows employing small size inductor and capacitors. The part is able to support all−ceramic−capacitor applications.
