The NCP5393AMNR2G from ON Semiconductor is a multiphase synchronous buck regulator controller specifically designed for powering the Core and Northbridge of AMD microprocessors. This device offers user-configurable two, three, or four-phase regulation for the Core and an independent single-phase regulator for the Northbridge.
Key features include dual-edge PWM for rapid transient response, high-performance operational error amplifiers for simplified compensation, and dynamic reference injection. It supports a DAC range from 12.5 mV to 1.55 V with 0.5% accuracy for 0.8 V to 1.55 V. The VDD and VDDNB offset ranges are from 0 mV to 800 mV. The controller incorporates differential voltage and phase current sensing, with "lossless" inductor current sensing for both VDD and VDDNB outputs.
This controller is housed in a 48-QFN (7x7) package and is designed for surface mounting. It operates within a temperature range of 0°C to 70°C and requires a supply voltage between 4.75V and 5.25V, drawing a typical current of 25mA. The NCP5393AMNR2G meets AMD's Hybrid VR Specifications and is suitable for applications such as desktop and server processors, and high-end notebook PCs.
