Abstract: A DC/DC conversion circuit, adapted to convert a DC input voltage (Vin) to a DC output voltage (Vout), employs a PNP type of bipolar power transistor (7) as a synchronous rectifier element, to allow power-on through a simplified control circuitry (5) capable of sensing, automatically and at a high speed, the difference of potential across the switch.
This approach allows power to be transferred from the input to the output unilaterally, while automatically controlling the depth of saturation of the power transistor and regulating its base current.
