In common 48/24V power supply designs for industrial equipment, pressure margin, heat generation, and implementation labor are significant challenges. One solution to this is the introduction of a non-isolated DC/DC module that adopts GaN FETs and achieves a maximum output of 20A. This module contributes to shortening the startup period and reducing design labor through its "just place it" modular structure. ● Title "Realizing 'Short Lead Time and Low Risk' in High Power Design" ～80V Voltage Rating × GaN FET Equipped × Maximum 20A: "Just Place It Easy" Non-Isolated DC/DC Module～ ● Agenda - Part 1: Demand and Latest Trends in DC/DC Modules Basics and challenges of DC/DC design Value of "just place it" modules Market size and trends in 48/24V - Part 2: Introduction of New DC/DC Module Product Concept Product Overview (80V Voltage Rating × GaN FET × Maximum 20A) Performance comparison with other high voltage DC/DC module products (efficiency, temperature, size) Heat generation demonstration (actual measurements) Expected applications (embedded control in industrial machinery) Development schedule (subject to change)

The semiconductor fundamentals course by Nisshinbo Micro Devices has received positive feedback with numerous participants each time. This time, we will hold a session titled "Teaching AFE (Basics)" – Understanding the Principles of ADC and How to Read AFE Data Sheets. Many people encounter situations where they have questions about how to read data sheets when using AFE. In this webinar, we will introduce how to read the AFE data sheets from Nisshinbo Micro Devices, assisting users in selecting the appropriate AFE. The difficulty level is beginner to intermediate, making it suitable for those who want to learn the basics of ADC, those who are unsure about selecting an AFE, and those who have questions. With recorded presentations and live chat Q&A with our engineers, even busy engineers can learn efficiently. ● Target Participants - Those who want to learn the basics of ADC - Those who have never used AFE - Those who are unsure about selecting an AFE - Those who want to know how to read AFE data sheets ● Agenda 1. Principles of ADC 2. Overview of AFE 3. How to Read AFE Data Sheets 4. Summary We look forward to your participation.

This webinar is designed to be helpful for those who want to understand the roles and movements of engineers involved in analog circuit design for the first time, engineers looking to deepen their understanding of op-amp characteristics, board evaluators, test engineers, and those newly responsible for component purchasing.
