Description

This reference design introduces a 5-V: 200-mA output Flyback DC-DC power converter targeting RS485 application in data concentrator.The 4000-VAC isolation power circuit is a simple and cost-effective solution as it uses a fully integrated converter TLV61046A and off-the-shelf transformer. The entire circuit is easy to copy into the system board to power RS485 device: greatly reducing the design time of circuit schematic and layout.Detail bench test results such as efficiency: load regulation and operating waveform are provided in the user guide for reference.
