Methods and apparatus for current sensing according to various aspects of the present invention operate in conjunction with a current sensor adapted to sense the current provided to a load via a transistor. In one embodiment, a power supply includes the current sensor, and supplies the current through a series combination of an inductor and the transistor. The current sensor is adapted to generate the inductor current signal according to a sensed current in the inductor, and may comprise a series combination of a first resistor and a second resistor. The resistive series combination is adapted to be connected in parallel to the series combination of the inductor and the transistor. |
