Title

A Novel Monolithic Self-Synchronized Rectifier

Abstract

A monolithic self-synchronized rectifier concept for DC/DC converter applications is presented in this paper. The smart rectifier integrated with a power MOSFET and control circuitry operates based on its drain-source voltage, and does not need external control input. The analysis, simulation, design considerations, and fabrication of the proposed concept are described in detail. Experimental results show that the proposed rectifier functions as designed. Since no dead-time control needs to be used to switch the SyncFET and CtrlFET, it is expected that the body diode losses can be reduced substantially comparing with the conventional synchronous rectifier. The proposed smart rectifier can be operated at high frequency and maintains high efficiency over a wide load range. © 2008 IEEE.
