Design of high-power buck-boost LED constant current drive circuit
Buck-boost constant current driving circuit is a flexible LED driving power supply, which can work properly in two modes of buck boost and boost. Buck-boost LED constant current drive circuit can adjust the operating mode according to vatiation of the load current to ensure that the output current is constant. The buck and boost topology structure is adopted as the main circuit of the drive circuit. The driving current of the experimental prototype is 2.5A and the output power is up to 30W. After a long time load test, the experimental results show that the designed circuit can work stably.
