Abstract: Using various techniques, each transistor in a DC-DC converter can have a corresponding voltage detector that can compare a difference of a first voltage at a first terminal of the transistor and a second voltage at a second terminal of the transistor to a threshold voltage. Then, based on at least one comparison, a controller can detect an open circuit or a short circuit in one or more of the transistors regardless of the direction of the load current in the DC-DC converter.

Abstract: A voltage regulator circuit comprises a switching circuit, a dynamic clamp circuit, and a comparison circuit. The switching circuit adjusts a switching duty cycle to produce a regulated output voltage using an error signal representative of a difference between a target voltage value and the output voltage. The dynamic clamp circuit determines a maximum peak inductor current command value using the output voltage and an input voltage of the voltage regulator circuit. The comparison circuit sets a maximum peak inductor current value using the maximum peak inductor current command value and a slope compensation current, wherein the maximum peak inductor current value is constant for different values of output voltage. The comparison circuit compares a sensed inductor current to a peak inductor current value and enables switching of the voltage regulator system according to the comparison.

The auto-zero amplifier circuit can generate an auto-zero compensation signal using a difference between the reference voltage stored on the additional capacitor and a voltage stored on another auto-zero capacitor.
