Design of a 1.5V Output Voltage On-Board DC/DC Converter with Magnetic Components Integrated in a Multilayer PCB

چکیده
Computer and telecommunication systems tend to demand lower supply voltages than 3.3V. This fact raises the challenge of obtaining high efficiency DC/DC converters with low output voltage. We have implemented a compact converter with an output voltage of 1.5V. The output power is 5W and the 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 to reduce the size. Self driven synchronous rectification allows to obtain very high efficiency (81.2% at nominal conditions, 85.3% maximum) for such a low output voltage.
