Abstract
This specification discloses devices and methods that provide for an improved switched mode power supply (SMPS) with a supply voltage connected p-type active clamp. In some embodiments, such an improved SMPS can have a p-type active clamp connected on one side to a positive voltage (which can preferably be the supply voltage), and on the other side to a clamp capacitor. Such an improved SMPS would then have the benefit of not requiring additional components (such as a level shifter, a high side supply voltage, a negative supply voltage, etc.) and the costs associated with these additional components.
