This is an article about how I used CAD to create a board pattern when producing a printed circuit board.

This is an article where you can see how the board pattern that I created was reviewed by a senior colleague when I was producing a printed circuit board, and how the board pattern was modified.

This article introduces the types of DC/DC converters, which are power ICs.

This article introduces how to select DC/DC converters and inductors, which are peripheral components.

This article introduces the difficulties and things I learned when designing a DC/DC converter board.

This article introduces the difficulties and points to be careful about when implementing a DC/DC converter.

This article introduces how the device works by actually evaluating it, and the need for a setting method that suits the purpose when evaluating it.

The final article is a bonus article that introduces some of the other things I worked on during my internship.

This article introduces how to consider specifications when creating a DC/DC converter circuit.

This is an article that explains how to prepare a DC/DC converter circuit before implementing it.

Basics of LTspice <Free>

Part 1:
As the basics of LTspice, you will learn how to set up the tool bar and control panel, how to run simulations using RC circuits, and analysis commands.

part 2:
You will learn how to generate a BOM of a power supply circuit, how to calculate efficiency, and how to evaluate it, starting with a simple simulation execution method using a sample circuit.
We will also explain how to add parametric analysis and diode models.

・ Those who have never used LTspice or those who are just starting to use it

・Those who use Analog Devices products

・ Those who want to obtain information on the latest Analog Devices products

We will explain the points of DC/DC converter circuit design using a power supply IC from Analog Devices.

This section explains in an easy-to-understand manner how to select a power supply IC and how to select peripheral constants. In addition, we will explain the important points about the layout of the board, which is the most important in power supply circuit design.

Even those who have never started power supply circuit design can participate.

・Those who are new to DC/DC converter circuit design

・Those who use Analog Devices products

・ Those who want to obtain information on the latest Analog Devices products

Recently, when I support customers, I often see high-density mounting boards with FPGAs with large internal circuits and only power supply circuits. As a result, the heat-generating FPGA and the power supply circuit are placed close to each other, and the entire board heats up, making thermal design difficult. In order to bring out the full performance of the product and maintain its reliability, it is very important not to rely only on the case design, but on the thermal design on the board.

In this seminar, we will introduce how to estimate the junction temperature using θJA and θJC, and the pitfalls of thermal calculation that have occurred recently.

• ・Those who want to know how to calculate the junction temperature
• ・Those who want to know how to measure junction temperature
• ・Those who want to practice heat calculation
• ・Those who want to know examples of problems caused by heat
