Abstract
A boost converter includes an input terminal, an output terminal, a switching terminal, a low-side transistor, and a down-mode detection circuit. The low-side transistor is coupled to the switching terminal. The down-mode detection circuit is coupled to the low-side transistor. The down-mode detection circuit is configured to detect a voltage at the output terminal greater than a voltage at the input terminal, and turn off the low-side transistor based on the voltage at the output terminal being greater than the voltage at the input terminal.
