Marubun Corporation (CEO: Hiroshi Horikoshi, Headquarters: Chuo-ku, Tokyo, hereinafter Marubun), an electronics trading company, will hold a free online seminar on July 14 (Tue) explaining the simulation of power supply circuits using LTspice. In this seminar, you can learn how to operate "LTspice," an analog circuit simulator provided by Analog Devices, Inc., while viewing the actual software screen. Using the simulation model of the DC/DC converter ADP2371, we will explain how to set up simulations for load response characteristics, which are important for evaluating power supply circuits. In the latter half, we will explain how to draw Bode plots on LTspice using the new "FRA tool" in the latest version LTspice24 to simulate the stability and response of power supply circuits. This seminar aims to help beginners of LTspice, those who want to know about new features, and those considering power supply circuit simulation to learn basic LTspice operations and power supply circuit simulation methods.
