Methods and apparatuses are provided for monitoring an inductor output
current delivered to a load by a power converter. For example, there is
provided an apparatus comprising: at least one power switch operatively
coupled to an input voltage source; an output inductor operatively
coupled to the at least one power switch and to the load; and a current
sensor operatively coupled to the output inductor, the current sensor
providing a current sense signal corresponding to the inductor output
current delivered to the load. In one embodiment, the current sensor
comprises: a filter comprising a first resistor coupled in series with a
first capacitor; and a second capacitor coupled in parallel with the
first resistor, the first and second capacitors forming an AC voltage
divider to increase the signal-to-noise ratio of the current sense
signal.
