Abstract
Computer and telecommunication systems tend to demand lower supply voltages than 3.3 V. This fact raises the challenge of obtaining high efficiency DC/DC power converters with low output voltage. The authors have implemented a compact power converter with an output voltage of 1.5 V. The output power is 5 W and the power converter has been provided with galvanic isolation between input and output sides. The windings of the magnetic components are directly integrated in the PCB, which allows a reduction in size. Self-driven synchronous rectification allows one to obtain very high efficiency (81.2% at nominal conditions, 85.3% maximum) for such a low output voltage.
