Smart power stage circuit for power converter with current monitoring
A recently granted patent (Publication Number: US12009749B2) discloses a smart power stage (SPS) circuit for a power converter. The SPS circuit includes an output stage circuit that receives an input voltage to provide an output voltage and inductor current, along with a driver featuring a driving circuit for pulse-width modulation (PWM) signals. The circuit also incorporates a monitoring signal generation circuit that produces a simulated current signal related to the inductor current. A compensation circuit generates a compensation signal when the simulated current signal exceeds a default value, enhancing the circuit's efficiency and performance.
Furthermore, the patent details a current monitoring circuit designed for the SPS circuit of a power converter. This monitoring circuit includes a monitoring signal generation circuit that generates a simulated current signal based on input and output voltages, along with a compensation circuit that adds a compensation signal when the simulated current signal surpasses a default value. The circuit's design allows for precise monitoring and control of the inductor current, ensuring optimal operation. Additionally, the monitoring circuit can switch between simulated and sensing current signals based on a PWM signal, enhancing flexibility and adaptability in various operating conditions.
