Abstract
A low power-loss supply circuit minimizes the losses in a synchronous rectifier power conversion circuit by regulating the voltage supply (Vcc) of a synchronous rectifier controller. The low power-loss supply circuit uses two regulating capacitors to regulate the value of the voltage supplied to the controller. A first regulating capacitor supplies the input voltage which powers the synchronous rectifier controller. A second regulating capacitor is used to cyclically charge the first regulating capacitor.
