PM6692:Two phase controller for Intel MVP7 GPU and CPU power supply

The PM6692 is a two phase step-down switching controller with embedded gate drivers. It has been designed to supply the CPU and GPU of the Intel® mobile platform, according with INTEL MVP7 specifications.

The controller is based on clocked constant on-time (CkCOT) architecture that allows nearly constant switching frequency over load.

The controller ensures 180° phase shift PWM operation when all the 2 phases are enabled.

An embedded integrator control loop compensates the DC voltage error due to the output voltage ripple. Load line of the output voltage can be adjusted by setting a resistor divider and it can be thermally compensated by using 1 NTC.

Current monitor IMON provides an analog output current proportional to the CPU load current. 1NTC can be used to sense the maximum temperature of the switching regulator and provide the temperature information to the CPU through SVID bus.

Adjustable VID transitions feature, TOT feature, extremely low shutdown and quiescent current make the PM6692 a very flexible and cost-effective solution for IMVP7 CPU power supply.
