I built the LT1248 circuit according to the data, and used 1mH inductor. Other parts were built according to the data. The switch tube always blew up at startup. It didn't help to reduce the chip oper...
1. The power supply part converts the mains power ~220V we use into the voltage required by the ECU and the voltage required by the stepper motor. This module has low requirements and can be completed...
Before talking about my trip to the TI Shanghai Seminar, I must thank Ms. Soso from the forum for informing me about the event, and I also want to thank Mr. Ma for his great help at the venue! Thanks ...
Detailed explanation of the principle of voltage doubler circuitNote: To understand the voltage doubling circuit, we must first consider the charged capacitor as a power source. It can be connected in...
Hi everyone, I am trying to connect to PC via ActiveSync using serial port under CE5.0. At present, when running repllog.exe under CE5.0, COM4 outputs CLIENT string, but ActiveSync on PC cannot detect...
After learning SIMPLE SWITCHER, let me talk about my feelings! SIMPLE SWITCHER is suitable for space-constrained load point design, so it has its unique advantages in a wide range of fields such as in...
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
