Title: Synchronous CMOS rectifying circuit for step-up devices

Abstract: Presented is a DC/DC converting circuit adapted to convert a DC input voltage to a DC output voltage. The converting circuit uses, as its synchronous rectifier member, a PMOS bipolar power transistor of the PMOS type, and allows it to be turned on by a control logic circuit capable of quickly sensing automatically the difference in electric potential between a conduction terminal and the body terminal of the transistor.
