The schematic diagram below shows a flyback converter using the BJT controller LNK4004D. The circuit is designed to operate from 185 VAC to 290 VAC (withstand 440 VAC for indefinite time at full load) ...

To save energy and reduce the size and weight of equipment, higher efficiency and power density are required in flyback converter-based LED drivers, chargers, and other power applications. The flyback ...

LEDs have come a very long way in performance and “comfort factor” in the past few decades for many good reasons. At the same time, the basic ac-line LED “supply” consisting of an ac/dc voltage-output ...
