NCP5386BMNR2G Description
In order to power both AMD and Intel processors and chipsets, the NCP5386BMNR2G is a one- or two-phase buck controller that combines differential voltage and current detection with adaptive voltage placement. By offering the quickest initial reaction to transient load events, dual-edge pulse-width modulation (PWM) in conjunction with inductor current sensing lowers system costs. Reduced total bulk and ceramic output capacitance is needed to satisfy transient load-line regulation thanks to dual-edge multi-phase modulation. A high-performance operational error amplifier is offered, enabling simple system adjustment. The error amplifier compensation becomes essentially independent of the system reaction to VID thanks to the patented Dynamic Reference Injection technique. trade-offs between overshoot and dynamic VID performance are eliminated.
