In view of LHC experiment upgrades we are developing a custom ASIC DC/DC converter for a new and more optimised detector power distribution scheme. The converter has been designed to be radiation tolerant and resistant to the experiment's high magnetic field. In this seminar some important design steps will be presented: the research of a suitable commercial technology, design with high and low voltage transistors, efficiency optimisation and air core inductor development. Since the design pathway is not always straightforward, some parasitic dangers we have discovered will be shown.
