This design note presents a schematic and a photograph of the top-side layout for the UCC3889 Off-Line Bias Supply Controller IC Evaluation Kit. This board accepts both conventional "through-hole" or leaded components as well as their surface-mount counterparts. An additional prototyping area allows engineers to further customize these units to address their projects' specific needs.

The UCC3889 controller is an off-line, low-power, low-voltage, regulated-bias power supply. The unique circuit topology in this device can be visualized as two cascaded flyback converters, each operating in the discontinuous mode, and both driven from a single external power switch. The significant benefit of this approach is voltage conversion ratios of 400V to 12V, with no transformer and low in
