Abstract
An isolated buck converter for converting an analog input voltage to an analog output voltage is capable of transferring digital data from the primary side to the secondary side. The converter comprises, on a primary side, a primary winding and a non-isolated buck connected in series, and a pair of switches switchable between a forward phase and a fly-buck phase. A secondary winding, on a secondary side, is inductively coupled to the primary winding, and a first capacitive element is connected over the secondary winding. The output voltage is achieved as the voltage over the first capacitive element. Further, the converter comprises, at the secondary side, supplementary circuitry by aid of which digital data can be transferred from the primary side to the secondary side.
