20100072964 | VOLTAGE REGULATOR INCLUDING CONSTANT LOOP GAIN CONTROL - A voltage regulation circuit includes a power stage for generating a regulated output voltage responsive to an input voltage and at least one PWM signal. A voltage divider circuit is connected to the output of the power stage and generates a feedback voltage. First circuitry generates the at least one PWM signal responsive to a voltage error signal, a filtered output voltage signal and a ramp voltage signal. The filtered output voltage is used for substantially removing loop gain change caused by the voltage divider circuit. A voltage compensation circuit generates the voltage error signal responsive to a feedback voltage and a reference voltage. | 03-25-2010 |

20100201405 | DYNAMIC PHASE TIMING CONTROL FOR MULTIPLE REGULATORS OR PHASES - A drive control circuit generates switching drive signals for a single phase of a multiphase voltage regulator. A driver circuitry generates the switching drive signals for the voltage regulator responsive to a clock signal. A clock circuitry generates the clock signal responsive to a monitored external clock signal. A phase number detector determines a number of active phases in the multiphase voltage regulator in real time responsive to an indicator on a phase number input monitored by the phase detector. | 08-12-2010 |
20110115450 | SYSTEM AND METHOD FOR CONTROLLING START UP OF A VOLTAGE REGULATOR SYSTEM WITH INDEPENDENT VOLTAGE REGULATION - A multichannel voltage regulator includes a plurality of voltage regulator modules for generating a regulated output voltage responsive to an input voltage and a feedback voltage. Synchronization circuitry controls a release of PWM signals during soft start within each of the plurality of voltage regulator modules. The PWM signals release are synchronized to occur substantially at a same point in time. | 05-19-2011 |
