1.1kW ITTF(Interleaved Two Transistor Forward) AC-DC Converter for Servers

This design is an AC-DC converter for servers that generates DC 12V from an input of AC 90 to 264V and delivers up to 1.1kW output.
It is equipped with an output ORing circuit, enabling redundant operation.
Components are selected with consideration for height when mounted on a PCB, making it suitable for use in 1U-sized power supplies.
We provide design information including key circuit design points, usage instructions, adjustment methods for each section, circuit diagrams, and PCB layout data to support your development.
