 Hi, I'm Greg Gomkowski from ST Microelectronics, and I'm here today to show you our digital power conversion demo. It's based on our popular STM32 microcontroller. In this case we're highlighting our STM32 F334, which is our microcontroller with the rich analog content peripheral set as well as a very high resolution timer. The F334 is a 72 MHz Cortex-M4 based product, as I said a rich analog peripheral set, and the board that we're demonstrating here today with it is our popular Discovery Board series. The F334 Discovery Board is demonstrating two applications. The first one is a PWM LED dimming application, and the second one is a buck-boost converter power conversion demo. The second demonstration we have here is on this plaque on the wall, and what we're showing here is a design with a LLC topology, and the switching frequency on this is at 1 MHz, which is giving very good power density, reduced passive components, and even electrolytic free design. And this kit is demonstrating our Nucleo board mounted with the F334, and this board is providing the digital control. Underneath it is the load board, which is a buck converter with load cells on it, and this can be used for evaluation purposes, or we also use in our workshops that we put on with Berea. So if you need more information please visit us on ST.com, and thanks for your attention.
