STMicroelectronics L6668 is an isolated flyback converter IC designed for offline power supply applications. This component operates at a 100kHz switching frequency and features an integrated 70% duty cycle. The L6668 incorporates essential control features including frequency control and soft start, alongside robust fault protection mechanisms such as current limiting, over-temperature, and over-voltage protection. It operates within a supply voltage range of 9.4V to 22V, with a startup voltage of 13.5V. The device utilizes a 16-SOIC (0.154", 3.90mm Width) package for surface mounting. Its isolated output is characteristic of flyback topologies, making it suitable for use in consumer electronics, industrial automation, and lighting control systems. The operating temperature range is -25°C to 150°C (TJ).
