A LED driving power supply based on buck-boost cascade quadtype buck topology
A novel LED driver is proposed and analyzed in this paper. The main circuit topology is based on a quadratic buck and a buck-boost. They share a switch through cascading, simplifying the topology and control strategy, reducing the cost of the control circuit. Using two-stage cascade structure, the i...
