A self-biased non-isolated buck regulator is provided. The regulator may include a first input terminal and a second input terminal, a high-voltage switch coupled to the first input terminal, a low-voltage switch coupled to the high-voltage switch, an inductor having a first terminal coupled to the high-voltage switch and the first low- voltage switch, a high-voltage rectifier diode coupled between the first low-voltage switch and the second input terminal, a second low- voltage switch coupled to the first low- voltage switch and the high-voltage rectifier diode, and a capacitor having a first terminal coupled to the first terminal of the inductor, and a second terminal coupled to the second low-voltage switch. 本发明提供了一种自偏置非隔离降压调节器。该调节器可包括第一输入端子和第二输入端子、耦接到该第一输入端子的高电压开关、耦接到该高电压开关的低电压开关、具有耦接到该高电压开关和该第一低电压开关的第一端子的电感器、耦接在该第一低电压开关和该第二输入端子之间的高电压整流二极管、耦接到该第一低电压开关和该高电压整流二极管的第二低电压开关、以及具有耦接到该电感器的该第一端子的第一端子和耦接到该第二低电压开关的第二端子的电容器。
