  • Sensorless self-tuning digital current programmed mode (CPM) controller with multiple parameter estimation and thermal stress equalization
    Patent number: 8536842
    Abstract: A multiphase controller for a DC-to-DC power supply includes logic to estimate parameters for multiple phases that provide a combined output at a load. The estimated parameters include a current estimate and an effective resistance estimates for each phase so that a power estimate for each phase can be produced. The logic adjusts the operation of the phases using the power estimate for each phase.

  • Wide-input windowed nonlinear analog-to-digital converter for high-frequency digitally controlled SMPS
    Patent number: 7525471
    Abstract: In embodiments, a new analog-to-digital converter (ADC) architecture can be used with switch-mode power supplies (SMPS) operating at switching frequencies higher than 10 MHz. Analog-to-digital converter embodiments can achieve very low power consumption, fast conversion time, and can be implemented with a simple hardware. Another noteworthy benefit is that certain ADC embodiments feature a non-linear gain characteristic that provides improved load transient response for digital controllers.
