Abstract
A voltage converter circuit with a self-oscillating half-bridge configuration has a first and a second input terminal, and a first and a second output terminal, and including: a first power switch coupled between the first input terminal and the first output terminal, a second power switch coupled between the first output terminal and the second input terminal, a first voltage sensor having a first and a second sensing terminals coupled between the first input terminal and a control terminal of the first power switch, and a second voltage sensor having a first and a second sensing terminals coupled between the first output terminal and a control terminal of the second power switch. Each voltage sensor detects a voltage variation supplied on its respective first sensing terminal and generates on the respective second sensing terminal an activation potential for the respective power switch.
