Zusammenfassung:	This paper describes design and implementation of a high switching frequency digitally controlled boost converter. A mixed control approach is applied to reach a high performance. An FPGA based implementation with 1 MHz switching frequency is build to verify the control methodology, and two controllers with 1 MHZ and 10 MHz switching frequency is applied on silicon. The raising edge of Vout to drive four LEDs is less than 100 mus.
