Abstract
A switch mode regulator circuit is provided to facilitate the conversion from one voltage level to another in a substantially power lossless manner. The circuit is particularly advantageous in instances where the power supply can be operable in a discontinuous mode, as inductor-capacitor oscillatory transients ("ringing"), along with its associated voltage spikes at the associated output transistor source, can be avoided. Such transients and their associated voltages are avoided by clamping the gate-source voltage on the circuit's output NMOS transistor over the entire positive operation voltage range.
