Abstract: A phase current estimator for a switching power converter includes analog circuitry for generating a phase current estimate error by comparing a phase current of the switching power converter to an analog representation of an estimate of the phase current, the phase current having a sawtooth or triangular waveform. The phase current estimator further includes digital circuitry for revising the phase current estimate based on the phase current estimate error and a plurality of parameters associated with operation of the switching power converter, so that the phase current estimate tracks the sawtooth or triangular waveform of the phase current.

Abstract: A phase current estimator for a switching power converter includes analog circuitry for generating a phase current estimate error by comparing a phase current of the switching power converter to an analog representation of an estimate of the phase current. The phase current estimator further includes digital circuitry for revising the phase current estimate based on the phase current estimate error and a plurality of parameters associated with operation of the switching power converter. An estimator fault detection unit is provided for determining whether a difference between the phase current and estimate exceeds a threshold for indicating substandard phase current estimation.

Abstract: In accordance with an embodiment, switch driver includes a first switch driver configured to be coupled to a control node of a first switch, a second driver configured to be coupled to a control node of a second switch, and a first terminal and a second terminal configured to be couple to a boot capacitor. The first terminal is coupled between a boot input of the first switch driver and the second terminal is configured to be coupled to outputs of the first switch and the second switch. The switch driver further includes a voltage measurement circuit coupled to the first terminal and the second terminal, and a control circuit configured to activate the second switch driver when the voltage measurement circuit indicates that a voltage across boot capacitor is below a first threshold.
