Monitoring current in power switch devices

In one example, a method includes generating, by a main switching element of a device, a load current; generating, by a regulation loop of the device, a sense current proportional to the load current; directly converting, by an analog-to-digital converter (ADC) of the device, the sense current into...

More Information
Summary:In one example, a method includes generating, by a main switching element of a device, a load current; generating, by a regulation loop of the device, a sense current proportional to the load current; directly converting, by an analog-to-digital converter (ADC) of the device, the sense current into a digital sense current value; and outputting, by the device and to an external device, a digital representation of the load current based on the digital sense current value.
