NCP5392PMNR2G Description
In order to supply precisely controlled power for both Intel and AMD CPUs, the NCP5392PMNR2G offers up to a four-phase buck solution that includes differential voltage detection, differential phase current sensing, and adaptive voltage placement. Inductor current sensing and dual-edge pulse-width modulation (PWM) offer the quickest initial reaction to dynamic load events, which lowers system costs. Reduced total bulk and ceramic output capacitance is needed to satisfy transient regulation standards when using dual-edge multiphase modulation.
