Design Support Tool

IPD Design Navigator

The IPD Design Navigator (Free, User registration is not required) is a web-based tool for designing an AC-DC converter with our IPDs. This tool assists you in selecting a desired IPD, calculates the circuit constants of AC-DC converter block circuit using the selected IPD, and generates a circuit diagram of the converter based on your required specifications, thus reducing your time for power supply design significantly.
