Filed:

Jun 15, 2012

Appl. No.:

13/524087

Inventors:

Steven M. Mercer - Livermore CA, US
Ronil D. Patel - San Jose CA, US

Assignee:

TEXAS INSTRUMENTS INCORPORATED - Dallas TX

International Classification:

G05B 13/02

US Classification:

323318

Abstract:

Within an electronic device, a voltage regulator powers a load. The voltage regulator has adjustable operating parameters that can be set during operation of the electronic device. The adjustable operating parameters are set or reset in accordance with a state of the electronic device, or a portion thereof having the load, in order to optimize power usage. The state is selectable from at least three predetermined states. Values for the operating parameters are selectable from a plurality of sets of values. Each set of values corresponds to at least one of the predetermined states.

International Classification:

Abstract:

In described examples, a phase interleaver obtains (i) a first signal indicating a variance between a reference voltage and a regulated output voltage and (ii) a second signal indicating a voltage across an energy storage device. A voltage regulator includes multiple phase blocks collectively configured to generate the regulated output voltage. In a repeating cycle, (i) the voltage across the energy storage device is increased while the second signal is less than the first signal and (ii) in response to a determination that the second signal is greater than the first signal, the energy storage device is substantially discharged, multiple stages of a clock divider are transitioned in the phase interleaver, and a set of control signals is output from the clock divider. The control signals have a common switching frequency and a common switching period. The control signals control the phase blocks active in generating the output voltage.
