A semiconductor package comprising:
- a first die comprising a first section of a power converter;
- and
- a second die comprising a second section of the power converter,
- wherein the power converter comprises:
- a plurality of switches, and a Power Management (PM) circuitry to control operation of the power converter by controlling switching of the plurality of switches,
- wherein the PM circuitry comprises a first part and a second part,
- wherein the first section of the power converter in the first die includes the first part of the PM circuitry, and
- wherein the second section of the power converter in the second die includes the second part of the PM circuitry.
A system comprising:
- a first die comprising one or more of:
- a memory to store instructions, a processor to execute the instructions, or a wireless interface to facilitate communication between the processor and another system, the first die further comprising a first section of a Voltage Regulator (VR);
- and
- a second die comprising a second section of the VR,
- wherein the VR comprises:
- a plurality of switches, and a Power Management (PM) circuitry to control operation of the VR by controlling switching of the plurality of switches,
- wherein the PM circuitry comprises a first part and a second part,
