Abstract:
A converter stage having a control pin, an input voltage pin, an output pin, a ground pin, a high-side switch coupled between the input voltage pin and the output pin, a low-side switch coupled between the output pin and the ground pin, a current sensor configured to detect a current at the output pin, and control logic coupled to the control pin and the current sensor. The control logic is configured to control switching of the high-side and the low-side switches in continuous conduction mode, discontinuous conduction mode, and body braking control for the converter stage in response to a first signal received via the control line and a second signal received from the current sensor. A driver controls switching, based on the detected current and sequential event tracking, between an on state and an off state.
