Abstract

Systems and methods for Power Factor Correction (PFC) circuits are described. In various implementations, these systems and methods may be used to power the operation of any component of any electronic device. In an illustrative, non-limiting embodiment, a power supply may include: a power converter having a high-side switch, a low-side switch coupled to the high-side switch, and a bootstrap capacitor coupled between the high-side switch and the low-side switch; and a control circuit coupled to the low-side switch, the control circuit configured to activate the low-side switch and charge the bootstrap capacitor without changing an output voltage of the power converter.
