Point-of-Load Converter (POLCo)

Development of a radiation hardened POL converter for satellite communications


The Objective

The goal of this project is to develop a highly integrated point-of-load DC-DC converter to supply digital integrated circuits de-centrally with high currents. The design must be radiation hardened to be used in space satellites.

IHP’s Contribution

IHP is providing a radiation hardened CMOS technology including a dedicated high voltage LDMOS device. Moreover, integrated inductors required in this application will be improved by wafer post-processing. The POLCo chips will be manufactured in IHP's 0.25 µm low-cost SiGeBiCMOS technology SGB25.


This research is funded by the Federal Ministry of Education and Research and supervised by the German DLR (Deutsches Zentrum für Luft- und Raumfahrt).
