DC-DC DC-DC CONVERTER WITH A DYNAMICALLY ADAPTING LOAD-LINE

摘要

Systems, apparatuses, and methods are described for efficiently generating a stable output for transient loads on one or more components. In various embodiments, the power converter includes two feedback loops to separate stability and equivalent output resistance, which causes the bandwidth to be increased. The first loop includes a compensator that receives the output current of the amplifier. Additionally, the first converter and the first current mirror generate a target current based on the output current of the amplifier. Based on the target current, a number of 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 response time of the second loop. A second current mirror receives current from the second transducer and generates a dynamic adaptive feedback current, which dynamic adaptive feedback current flows through a resistor in the first loop.
