Abstract
An on-die multiple phase power converter reduces output voltage ripple and reduces input current ripple while allowing for higher input voltage and reduced input current to a circuit board. The on-die multiple phase power converter also allows for more than one supply voltage on a die. The converter includes a plurality of single phase switching blocks and a clock signal phase generator. The single phase switching blocks receive phase-shifted clock signals from the clock signal phase generator and provide an output voltage. The output currents of the single phase switching blocks may combine to form a single output to provide current to one or more functional unit blocks on the semiconductor die. One or more or the single phase switching elements may be combined to provide current to one or more functional unit blocks on the semiconductor die.
