Introduction The MX9008 is a dual-channel power management IC suitable for applications powered by USB or 5V DC adapters. It employs a high-efficiency synchronous buck architecture, and the internal compensation network simplifies circuit design. The buck converter operates in current mode control, supporting a constant switching frequency.The dual-channel 5.5V DC/DC buck power management unit (PMU) … Read more
1. Introduction It has been a while since the last article update, but the HPMicro CANFD tool project is still ongoing. For those unfamiliar with this project, you can refer to the article titled “Challenge: Can We Build a 4-Channel CANFD Analyzer for Under 40 Yuan? Practical Edition”. In open-source projects based on STM32, especially … Read more
