NCP81172
NCP81172 is 2-Phase Synchronous Buck Controller manufactured by onsemi.
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 pact- footprint power management solution for new generation puting processors. It receives power save mand (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.
