NCP5316中文资料Four/Five/Six-Phase Buck CPU Controller数据手册ONSEMI规格书

描述 Description

The NCP5316 provides full-featured and flexible control for the latest high-performance CPUs. The IC can be programmed as a four-, five- or six-phase buck controller, and the per-phase switching frequency can be as high as 1.0 MHz. Combined with external gate drivers and power components, the controller implements a compact, highly integrated multi-phase buck converter. Enhanced V2 control inherently compensates for variations in both line and load, and achieves current sharing between phases. This control scheme provides fast transient response, reducing the need for large banks of output capacitors and higher switching frequency.
