Description

This reference design uses the UCC28C42 in a non-isolated flyback topology to generate 3.3V, 1.2V and 22V from a US line AC input. The total output power is 4W. The 3.3V output is regulated by the UCC28C42. A TLV1117LV LDO is used to generate the 1.2V output from the 3.3V output. The 22V output is unregulated and designed only to provide 20mA.
