Abstract: A voltage regulator includes a high duty cycle detector, a feedback controller, a hysteretic comparator, and first and second drivers. The high duty cycle detector generates a high duty cycle signal based on a power supply voltage and a reference voltage. The feedback controller generates first and second feedback voltages based on the reference voltage, the high duty cycle signal and an output voltage of the voltage regulator. The hysteretic comparator compares the reference voltage and the first feedback voltage to generate a control signal. When the first feedback voltage is activated, the first driver drives an output node that provides the output voltage based on the control signal and the high duty cycle signal. When the second feedback voltage is activated, the second driver generates a third voltage proportional to the reference voltage based on the power supply voltage and the second feedback voltage, and drives the output node with the third voltage.

The voltage to current converter converts a sensing voltage to a first current, and the sensing voltage is sensed based on a current flowing through an output coil connected between a switching node and an output node. The current mirror circuit mirrors the first current to generate a second current and a third current, the second current is N times greater than the first current, the third current is M times greater than the first current, and N and M are real numbers greater than zero. The switch provides a feedback node with one of the second current and third current in response to a switching control signal, and an output voltage of the output node is divided at the feedback node.
