View the Important Notice for TI Designs covering authorized use, intellectual property matters and disclaimers.
This 4W reference design generates both a 3.3V and 12V output. The 3.3V output is regulated, while the 12V output has some load dependent variation. The UCC28740 flyback controller provides a low cost yet efficient solution.
