Claim 14:
15. A boost converter having a converter input and a converter output, the boost converter comprising:
an inductor having a first terminal coupled to the converter input, the inductor having a second terminal;
a first transistor having a first control input, a first current terminal, and a second current terminal;
an isolation transistor having a second control input, a third current terminal, and a fourth current terminal, the third current terminal coupled to the second terminal of the inductor;
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 isolation transistor and to control a voltage on the first control input of the first terminal based on the determined average current level; and
an isolation transistor driver having first transistor driver voltage terminal, a second transistor driver voltage terminal, a first transistor driver control input, a second transistor driver control input, and a transistor driver output coupled to the second control input, the first transistor driver voltage terminal coupled to the third current terminal, and the second transistor driver voltage terminal coupled to the fourth current terminal.
