Could you please help with completed QuickStart for the inverting design. It will help us in debugging if anything is quite right in schematic
你好，能不能帮我向工程师转述以下问题，
Generally speaking, when designing a flyback switching power supply, it is usually designed according to the default input of AC85-265V. The technical documents about TI also design the flyback switching power supply according to this…
This is non-isolated design. Function of flyback is just step down the 400V bus to various rails 15V/12V/5V etc not the isolation.
You need these two connected otherwise all sensing signals, GPIOs and PWMs won't have same reference.
If you isolate…
Part Number: UCC28740 Other Parts Discussed in Thread: PMP41009
Hello, I plan to use the UCC28740 chip to design a wide-range dual-transistor flyback converter with a structure similar to that of the PMP41009. Its specifications are as follows: output…
Other Parts Discussed in Thread: PMP41009 , UCC28740-Q1 , UCC28740 , UCC28742 Hi，May I ask if I can replace the UCC28740-Q1 chip in the PMP41009 design circuit with a chip from the UCCx8C5x series? If not, what is the reason? Can chips from the UCCx8C5x series…
Part Number: PMP41009 Other Parts Discussed in Thread: UCC28740 , Hello, I am debugging a self-designed flyback switching power supply with an input of 90-900VAC and an output of 24VDC. I use the UCC28740 chip and adopt the relevant power supply circuit…
