NCP81278DMNTXG Description
The NCP81278DMNTXG, a general?purpose two?phase synchronous buck controller, integrates gate drivers and PWM VID interface in a QFN20 package and provides a compact?footprint power management solution for new generation computing processors. It has a programmable power save interface (PSI) and is able to operate in 1?phase diode emulation mode to obtain high efficiency in light?load conditions. Operating in high switching frequencies up to 800 kHz allows for employing small-size inductors and capacitors. The NCP81278DMNTXG is able to support all ceramic-capacitor applications.
