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 1):
A current loop powered DC-DC converter comprising a transformer having a primary winding and a secondary winding establishing a primary side and a secondary side, the primary winding being connected to a transformer drive circuitry imposing a drive signal onto the primary winding, the secondary winding being connected to at least one rectifier, characterized in that the rectifier is realized as an active rectifier, comprising a FET-transistor and a rectifier drive circuitry arranged to provide a gate drive signal for the FET-transistor, which rectifier drive circuitry comprises a phase detector arranged to detect 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, an output signal of the phase detector being connected to a charge balance circuitry arranged to control by a charge balance circuitry output voltage a pulse length of the active rectifier FET transistor gate drive signal, which charge balance circuitry comprises a charge pump and a low pass filter.
