STMicroelectronics PM6652
The PM6652 is a single-phase, step-down SMPS controller with high precision 7-bit DAC. It has been designed to supply the CPU and the graphics core (render engine) of the Intel® mobile platform, according to Intel MVP6.5 specifications. The PM6652 can also be configured to supply the 7-bit family, VR11 compliant, ATOM® processors.FEATURES
