The NCP81278MNTXG is a synchronous buck D-CAP2™ mode controller specially designed to support multi-phase low voltage applications for CPU core, GPU core, I/O regulators, DDR, HBM2, or a mix of different voltages. The controller is supported by an integrated FET driver, OSD and fault protection functions, allowing it to alter the supply voltage and power to the system’s sensitive components in real time. This part is suitable for video cards and many other application fields due to its versatility and reliability.

The NCP81278MNTXG supports an operating frequency up to 1250KHz, allowing it to use small packages as well as low valued inductors and capacitors. With an input supply voltage of up to 21V, and an output voltage of up to 12V, this fully-integrated controller takes into consideration the needs of today and tomorrow’s multi-phase power conversion applications.

The NCP81278MNTXG offers impressive efficiency performance and a huge range of programmability. It supports adjustable switching frequency, voltage, dead time, and over current limit, allowing for easy multi-phase system optimization. All these features make the part a great candidate for multi-phase voltage regulation.

The NCP81278MNTXG offers a wide range of protection features, including significant protection against over-temperature, over-current, and short-circuit events. A safety timer, peak current limit and soft start limit/algorithm also come included. This allows the device to handle a wide range of applications, ensuring an optimum level of system performance and reliability.

The NCP81278MNTXG features a synchronous buck architecture, which allows the device to maintain high efficiency across a wide range of input and output voltages. A Zero-Voltage Switching Mode (ZVS) further improves performance by eliminating the large switch losses in the high frequency, and allows the device to reach higher frequency in order to minimize the inductors size.

The NCP81278MNTXG is an ideal choice for voltage regulation in multi-phase systems, such as graphics cards, CPUs, and other integrated circuits. The device’s integrated FET driver, OSD, easy programmability and a wide range of protection functions make it an excellent choice for any voltage regulation application.
