Abstract:
A power supply system (10) includes a pulse-width modulation (PWM) system (14) configured to generate a PWM signal. The system (10) also includes a power stage (16) comprising a gate driver (60), a high-side switch, and a low-side switch. The gate driver (60) can be configured to alternately activate the high-side and low-side switches to provide an output signal to a load (12) in response to the PWM signal, and to provide an activation dead-time between the alternate activation of the high-side and low-side switches. The system (10) further includes a digital delay system (18) configured to measure the activation dead-time and to add the measured activation dead-time to the activation of the high-side switch.
