摘要： In described examples, an integrated fluxgate device (100) has a magnetic core (110) on a control circuit (102). The magnetic core (110) has a volume and internal structure sufficient to have low magnetic noise and low non-linearity. A stress control structure (158) is disposed proximate to the magnetic core (110). An excitation winding (124), a sense winding (126) and a compensation winding (128) are disposed around the magnetic core (110). An excitation circuit disposed in the control circuit (102) is coupled to the excitation winding (124), configured to provide current at high frequency to the excitation winding (124) sufficient to generate a saturating magnetic field in the magnetic core (110) during each cycle at the high frequency. An isolation structure (152) is disposed between the magnetic core (110) and the windings (124), (126), and (128), sufficient to enable operation of the excitation winding (124) and the sense winding (126) at the high frequency at low power.

摘要： A multiphase power regulator (100) includes a plurality of phases coupled in parallel to provide a load current as a combination of phase currents at an output voltage (Vout), each phase including at least one power transistor switched to provide a respective phase current based at least in part on a comparator output signal, and a current-sense low pass filter to sense the phase current. The regulator (100) further includes a gm stage (102) to generate the current set point voltage based at least in part on the output voltage (Vout), a comparator (110) to compare a voltage from the current-sense low pass filters to the current set point voltage, and a current set point adjustment circuit (150) to provide an auxiliary control signal to decrease the current set point voltage responsive to a change in comparator output and then to increase the current set point voltage responsive to another change in comparator output.
