onsemi NCP5318
The NCP5318 provides full−featured and flexible control conforming to the Intel® VRM 10.1 specification for high−performance CPUs. The IC can be programmed as a two−, three− or four−phase buck controller, and the per−phase switching frequency can be as high as 1.0 MHz. This control scheme provides fast transient response, reducing the need for large banks of output capacitors and higher switching frequency.FEATURES
