NCP81278
Compact 2-Phase
Synchronous Buck
Controller with Integrated
Gate Drivers and PWM VID
Interface
The NCP81278, a general−purpose two−phase synchronous buck
controller, integrates gate drivers and PWM VID interface in a
QFN−20 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
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.
