Switched converter

A method for sensing a current flowing across output terminals of a switched converter supplying a light emitting diode load (LED load), wherein the switched converter comprises:

• at least one switch, the output terminals for supplying the LED load, an output capacitor (Cout) arranged in parallel to the output terminals, a current sensing transformer, a primary winding of the current sensing transformer, a secondary winding of the current sensing transformer, wherein the primary winding of the current sensing transformer is connected in series to the output capacitor (Cout);
• the method comprising the steps of:
• controlling the operation of the at least one switch;
• operating in alternating cycles between phases of supplying energy from a node on a potential of the at least one switch to the output terminals for supplying the LED load and for charging the output capacitor (Cout) and phases of supplying energy to the output terminals for supplying the LED load from the output capacitor but not from said node, characterized by the steps of:
• generating, by the secondary winding of the current sensing transformer, a sensor output signal;
• supplying the sensor output signal to a control circuitry of the switched converter;
• and
• during phases in which energy is supplied to the output terminals from the output capacitor (Cout) but not from said node, sensing, by the control circuitry, the current flowing from the output capacitor (Cout) across the output terminals supplying the LED load based on said sensor output signal.
