A low part count, efficient quasi‐resonant light‐emitting diode driver is proposed. The proposed driver relies on a capacitive safety isolation barrier, which eliminates the need for a bulky isolation transformer; thus, the footprint area can be reduced. Operation frequencies of 100–350 kHz further contribute to miniaturisation of the proposed driver. The feasibility of the proposed topology is verified by simulation and experimental results.
