Abstract:
The present invention relates to a current loop powered DC-DC switch mode converter for use as a local isolated low power supply for electronic circuits such as current loop transmitters where the requirements for supply efficiency and cost of the implementation is critical. It is the object of the invention to provide a simple and low cost solution for driving a synchronous rectifier thereby improving the supply efficiency, especially at low output voltages.

Claim (Index 19):
A method of controlling a current loop powered DC-DC converter, the DC-DC converter comprising a transformer having a primary winding and a secondary winding establishing a primary side and a secondary side, the secondary side comprising an active rectifier comprising a FET-transistor, the method comprising the steps of:\n imposing by a transformer drive circuitry on the primary side a drive signal onto the primary winding; generating by a rectifier drive circuitry on the secondary side a gate drive signal to control the FET-transistor; and regulating a pulse length of the active rectifier FET transistor gate drive signal by a charge balance circuitry output voltage on the basis of a phase difference between a representation of a pulse of a transformer transferred driver signal present at the secondary side of the transformer and a representation of a pulse of the gate drive signal for the active rectifier FET transistor; wherein the charge balance circuitry output voltage is controlled by a charge balance circuitry comprising a charge pump and a low pass filter.
