Low power multioutput converter with post-regulation based on synchronous rectification and windings integrated in the PCB

This paper presents the description and laboratory measurements of a low power flyback with self-driven synchronous rectification (SDSR) multioutput converter (6 outputs) with windings of transformer integrated in the PCB for a telecommunication application. In this converter two new methods for Post-regulation and overvoltage protection taking advantage of the MOSFETs of the SDSR have been applied in order to obtain high efficiency (>80%).
