Description
SD6900 is designed for non-isolated LED driving with floating
Buck structure.With this structure, inductor current will be
sensed and closed-loop is formed with the internal error
amplifier for high constant current accuracy and high
input/output regulation rate.Also, high PF in full range is
available as its own PFC control.Boundary Conduction mode is
adopted for decreasing switching loss and improving the
conversion efficiency.SD6900 integrates various protections, such as output
