Abstract: A smart power stage module includes an output stage and a driving circuit. The output stage includes a low-side switch and provides an output current. The driving circuit controls an operation of the output stage according to a PWM signal. The driving circuit includes a determination circuit generating a control signal according to the PWM signal and a signal combination circuit providing a current monitoring signal representing the output current. The current monitoring signal is a combination of a simulated current signal and an actual sensed current signal. The signal combination circuit includes a switching circuit switching according to the control signal to adjust a proportion of simulated current signal and actual sensed current signal. When the on-time period part of low-side switch is shorter than a default time period, the switching circuit shortens duration of simulated current signal in the current monitoring signal according to the control signal.

Abstract: A smart power stage (SPS) circuit of a power converter and a current monitoring circuit thereof are disclosed. The SPS circuit includes an output stage circuit and a driver. The output stage circuit receives an input voltage and the power converter provides an output voltage and an inductor current. The driver includes a driving circuit, a monitoring signal generation circuit and a compensation circuit. The driving circuit receives a PWM signal and provides a driving signal to the output stage circuit. The monitoring signal generation circuit receives the PWM signal, input voltage and output voltage for generating a monitoring signal related to the inductor current.
