The onsemi FPS™ FSL128MRTWDTU is an 800V offline flyback converter designed for high-efficiency power supply applications. This component features an integrated 67% duty cycle switch operating at a frequency of 67kHz, simplifying external component count and reducing board space. It offers robust fault protection including current limiting, overload, over-temperature, and over-voltage protection. The device is housed in a TO-220F-6L (Forming) package, suitable for through-hole mounting. Key operating parameters include a startup voltage of 12V and a supply voltage range of 7.5V to 26V. This flyback converter is ideal for use in consumer electronics, industrial automation, and lighting solutions where isolated power conversion is required. The FSL128MRTWDTU provides up to 40W of power with its isolated topology.
