PM6652 Single-phase multifunctional DC-DC controller for Intel platforms

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.

The controller, based on constant on-time (COT) architecture, allows real-time dynamic switching of the core operating voltages and frequencies, working in both performance and suspend render states.

An embedded integrator control loop compensates the DC voltage error due to the output ripple.

The high efficiency at light load, achieved with pulse-skipping working mode, and the extremely low shutdown and quiescent adsorbed current, make the PM6652 the ideal choice in battery powered devices
