    About the Author

    Frederik Dostal | Power-Management Technical Expert

    Frederik Dostal is a power-management expert with more than 20 years of experience in this industry. After his studies of microelectronics at the University of Erlangen, Germany, he joined National Semiconductor in 2001, where he worked as a field applications engineer, gaining a lot of experience in implementing power-management solutions in customer projects. During his time at National, he also spent four years in Phoenix, Arizona (USA), working on switch-mode power supplies as an applications engineer.

    In 2009, he joined Analog Devices, where since then he held a variety of positions working for the product line and European technical support, and currently brings in his broad design and application knowledge as a power-management expert. Frederik works in the ADI office in Munich, Germany.
