Abstract
A switching regulator includes at least two power switches and two rectifier switches, power transformer having a primary and secondary windings, control circuit for generating control pulses for the power switches, an inductor for providing output current to the load and connected, and a current sensor coupled to the secondary windings and the inductor for sensing current passing through the inductor. The current sensor preferably includes a first and second resistor and a capacitor connected together, and provides a sensed voltage at its output proportional to the product of output current of the inductor and inherent DC resistance of the inductor and the secondary windings. The current sensor is coupled to the control circuit for regulation and protecting the switching regulator against overload or short circuit conditions.
