In an embodiment a method includes receiving, at an input of a low-voltage section of a gate driver, a PWM control signal with a switching frequency, providing, at an output of a high-voltage section of the gat driver, a gate-driving signal as a function of the PWM control signal to a power stage, wherein the high-voltage section is galvanically isolated from the low-voltage section, receiving, at a feedback input of the high-voltage section, at least one feedback signal indicative of an operation of the power stage, converting, at an ADC module of the high-voltage section, the feedback signal into a digital data stream, providing, to the ADC module, a conversion-trigger signal designed to determine a start of a conversion for acquiring a new sample of the feedback signal and sending, via an isolation communication channel between the low-voltage section and the high-voltage section, the digital data stream to the low-voltage section.
