Other Parts Discussed in Thread: UCD3138
Hello,The《Using the UCD3138HSFBEVM-029 User's Guide》"A.5.2 Prebias Load and Load Synchronous Startup",tell us"The special technique, called Synchronous Startup, is used to enhance the parallelstartup performance of UCD3138 controlled converters. This technique uses a GPIO pin as sync-pin which connects each board together to start at the same time then the output voltage difference from different converter is minimized."
I have a question about the function of synchronous startup。How to design the hardware and the software to achieve synchronous start function?
