Fast transient response high-accuracy current-sensing technique for step-up DC–DC converter

A novel current-sensing technique with fast transient and high accuracy for a step-up DC–DC converter is presented. This circuitry is applied for sensing the current flowing through the equivalent series resistor (ESR) of the inductor to obtain the inductor current information. It is achieved with a...
