Abstract
A switch-mode power supply includes a drive transistor, an inductor, and a compensation network. The drive transistor includes a drive transistor current output terminal. The inductor includes an inductor input terminal and an inductor output terminal. The inductor input terminal is coupled to the drive transistor current output terminal. The compensation network is disposed across the inductor. The compensation network is configured to detect voltage drop across the inductor, and to conduct a current from the inductor output terminal to the drive transistor current output terminal.
