onsemi NCP5316
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. This control scheme provides fast transient response, reducing the need for large banks of output capacitors and higher switching frequency.| Part No. | NCP5316 |
