Abstract:
1. A flyback converter having temperature compensation, the converter comprising: a transformer having a primary winding and a secondary winding, the primary winding being part of a primary side of the converter, and the secondary winding being part of a secondary side of the converter, wherein the primary side is isolated from the secondary side such that the converter is an isolated converter; a power switch coupled to the primary winding, wherein a duty cycle of the power switch controls an output voltage of the converter; a primary side sensing circuit on the primary side and an output diode on the secondary side, the output diode having a variable voltage drop related to its temperature, the primary side sensing circuit comprising an output voltage sense circuit sensing a first voltage generated on the primary side of the transformer when the power switch is off and outputting a feedback voltage V the converter generating the feedback voltage V
