The NCV81275AMNTXG from ON Semiconductor is a multiphase synchronous buck controller optimized for advanced computing and graphics processors. This device is capable of driving up to 8 phases, incorporating differential voltage and phase current sensing for accurate power regulation. It features a wide supply voltage range of 4.5 V to 20 V and a switching frequency of 250 kHz to 1.2 MHz when operating with 8 phases.
The controller includes essential protection features such as Under Voltage Protection (UVP), Over Voltage Protection (OVP), and Over Current Protection (OCP). It supports a Power Saving Interface (PSI) for improved light-load efficiency and offers PWM_VID and I2C control interfaces. The NCV81275AMNTXG is housed in a compact 40-pin QFN wettable flank package, suitable for surface mount applications.
Designed for applications like GPU and CPU power, and automotive systems, this controller operates reliably within a temperature range of -40°C to +105°C. It is AEC-Q100 Grade 2 approved and is Pb-Free, Halogen Free/BFR Free, and RoHS Compliant.
