STMicroelectronics PM6690
The PM6690 is a three phase step-down switching controller with embedded gate drivers. It has been designed to supply the CPU of the Intel® mobile platform, according with INTEL MVP7 specifications. The controller is based on clocked constant ontime (CkCOT) architecture that allows nearly constant switching frequency over load.| Part No. | PM6690 |
