Claim 9:
10. A voltage converter having a voltage input and a voltage output, the voltage converter comprising:
a first transistor having a first control input, a first current terminal, and a second current terminal;
a second transistor having a second control input, a third current terminal, and a fourth current terminal, the third current terminal adapted to be coupled to an inductor; and
an average current control circuit coupled to the third current terminal and the fourth current terminal, the average current control circuit configured to determine an average current level of current flowing through the second transistor and to control a voltage on the first control input of the first transistor based on the determined average current level, wherein the average current control circuit includes a current sense circuit having first and second current sense circuit inputs, the first current sense circuit input coupled to the third current terminal, and the second current sense circuit input coupled to the fourth current terminal.
