Abstract
A driver circuit for controlling a high-power switch. The driver circuit comprises a flyback converter and a driving stage. The flyback converter includes a controller that configured to: receive a PWM control signal, which is for controlling the high-power switch; receive a feedback voltage signal, representative of a measured voltage of a positive output rail or the negative output rail of the flyback converter; and provide a primary-side switch control signal that comprises a bursts of pulses for operating the primary switch, wherein the controller is configured to start a burst of pulses in response to an edge of the PWM control signal, and stop the burst of pulses in response to the feedback voltage crossing a threshold. The driving stage is connected between the positive output rail and the negative output rail. The driving circuit is configured to provide a high-power switch control signal for controlling the state of the high-power switch based on the PWM control signal.
