`U.S. Patent No. 8,477,514 – Dell LA90PM170
`
`Claim 16
`A method of operating a (SYS) power system, comprising:
`enabling operation of components of a (PRO) processor system to establish a (DRN) state of power drain thereof;
`providing a (COM) signal to identify (OPN) operation of said (PRO) processor system in said (DRN) state of power
`drain;
`sensing a (PL) power level of said (DRN) state of power drain in response to said (COM) signal; and
`controlling an (IOC) internal operating characteristic of a (PC) power converter as a function of said (PL) power level.
`
`Claim 17
`
`The method as recited in claim 16, further comprising:
`inducing a (PS) power switch of said (PC) power converter to conduct for a (DC) duty cycle to provide an (OC) output
`characteristic at an (OUT) output thereof; and
`controlling said (DC) duty cycle of said (PS) power switch dependent on said (OC) output characteristic and in
`accordance with said (PL) power level.
`
`Claim 19
`The method as recited in claim 16 wherein said controlling said (IOC) internal operating characteristic comprises occurs
`over a (TTIM) period of time.
`
`Claim 20
`The method as recited in claim 16 wherein said (IOC) internal operating characteristic is selected from the group
`consisting of:
`a (GDV) gate drive voltage level of said (PS) power switch of said (PC) power converter,
`a switching frequency of said (PC) power converter, and
`an (DCBV) internal direct current bus voltage of said (PC) power converter.
