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

摘要

Disclosed are systems, apparatuses, and methods for efficiently generating a stable output for a transient load for one or more components. According to various embodiments of the present invention, a power converter includes two feedback loops to separate stability and equivalent output resistance, which increases bandwidth. 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, a plurality of step-down converters generate an output voltage. The output voltage is returned to the amplifier through a resistor. The second loop includes a second converter with a first order series RC filter to reduce response time of the second loop. A second current mirror receives a current from the second converter and generates a dynamically adapting feedback current. The dynamically adapting feedback current flows through the resistor in the first loop.
