Please help me find a voltage regulator diode. The requirement is 0.5W 4.7V. When the input voltage is 4.5V, the leakage current must be less than 0.2mA. I asked 3 manufacturers and none of them met m...
At present, there are three main methods for LED to achieve white light: 1. Synthesize white light through the LED red, green and blue three-primary color multi-chip set and light emission. Advantages...
I have just started learning electronic design and will participate in an electronic design competition next year. I want to learn about FPGA, but I don’t know where to start. I hope to get some advic...
All electronic design engineers and scientists have performed electrical signal analysis, or signal analysis for short. Through this basic measurement, they can gain insight into signal details and...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
