Abstract
Systems, apparatuses, and methods for efficiently generating a stable output for a transient load for one or more components are described. In various embodiments, a power converter includes two feedback loops to separate the stability and the equivalent output resistance, which allows the bandwidth to increase. The first loop includes a compensator receiving an output current of an amplifier. Additionally, a first converter and a first current mirror generate a target current based on the output current of the amplifier. Based on the target current, multiple step-down converters generate an output voltage, which is returned to the amplifier through a resistor. The second loop includes a second converter with a first order series RC filter to reduce the second loop's response time. A second current mirror receives current from the second converter and generates a dynamically adapting feedback current, which flows through the resistor in the first loop.
