Abstract : The power consumption of embedded microprocessors has increased significantly due to the considerable number of new functions which they should manage. Thus, current generation of microprocessors needs considerable supply currents with very low voltages. The aim of this dissertation is to study these supply modules and their association to increase the current supply levels delivered to the charge. These power supply systems are oriented to embedded microprocessors like those can be found inside PC motherboards.. Traditionally, this kind of power supplies owns analogue control. However, new microprocessor generation demands faster performances and more accurate and tight regulations. Thus, the present trend is to replace the classical analogue control by a digital control system more flexible and performing likewise. Then, this dissertation takes part in the LISPA regional project where the LAAS and Freescale Semiconductor collaborate to develop new power supply systems for embedded power microprocessors.
