摘要

The high power LED driver based on non-inverting buck-boost converter is considered in this paper. The special regulation approach of this converter is described in order to simplify the control strategy. Thus, the implementation of this control strategy in microcontroller based closed loop regulation system allows to increase number of regulation steps (to achieve higher resolution) and to utilize timers of the microcontroller in more efficient way. Also the considerations on the configuration of MOSFET gate driver circuits are given in the paper.
