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.

Abstract: A device includes a current mirror, a switch, first and second current paths, first and second buffers, a variable resistor, a temperature-sensing circuit, and a controller. The first current path is coupled between the current mirror's input and the switch. The switch switches between ground and a transistor based on a control signal. The second current path is coupled between a first current mirror output and ground. The first buffer is coupled to a second current mirror output. The second buffer is coupled to the variable resistor, which is coupled to the first buffer. The temperature-sensing circuit provides a device temperature to the controller, which is coupled to a first buffer output and determines a first adjustment to the first and second current paths and a second adjustment to the variable resistor based on the device temperature.
