depends on what you want. if you only care about the average current, you can leverage the serial resistance in the winding. If you want to do a real time measurement, that may depends on your actual circuit. For example, if it is a buck/boost, like someone mentioned, you can sense the mosfet current .

mosfet is offchip, how can I sense the mosfet current?
real current

【在 h*******l 的大作中提到】 : There is another way to do it on earlier power ics. : Use RC to be in parralel with inductor.voltage cross c is proportional to : inductor current.
