  • Adjusting voltage regulator operating parameters
    Patent number: 9088174
    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.
    Type: Grant
    Filed: June 15, 2012
    Date of Patent: July 21, 2015
    Assignee: TEXAS INSTRUMENTS INCORPORATED

  • Power Converters Having Varied Switching Frequencies
    Publication number: 20130020870
    Abstract: Systems and techniques for performing power conversion operations in a portable device are used to convert an input voltage to a voltage at an output. The conversion operations use a two-stage conversion to convert the input voltage to a first voltage and to convert the first voltage to a second voltage. A switching frequency is altered with changes in the input voltage. The switching frequency is selected based on the input voltage level and/or to maintain a substantially consistent ripple at the output, which can correspond to the first voltage and/or the second voltage.
