Fixed Frequency Quasi-Resonant Buck and Tap Buck Converters

Description:
This invention proposes two novel Buck type converters to achieve no body diode loss for the synchronous rectifier in non-isolated Buck DC/DC converters.  In addition, their top switches can also be achieved soft switching.  All of these features guarantee these circuits suitable for high frequency and low voltage high output current applications,  12V-input VRM in the desktop is the good example to apply this invention.
