Other Parts Discussed in Thread: UC1875-SP , UC1875 I I'm looking for information regarding the uc1875-sp sync circuit. Figure 4 of the uc1875-sp datasheet shows a schematic, but there are enough details missing that I cannot simulate the circuit. What…
Other Parts Discussed in Thread: UC1875-SP , UC1875 Hi All,
I am working on a phase-shifted, DC-DC full bridge design using the UC1875-SP controller IC.
I chose the UC1875-SP because I needed a rad-hard, space qualified (Class V) controller, and the UC1875…
Other Parts Discussed in Thread: UC1875 I Plan to use the radiation tolerant UC1875 in a new design.
I wish to use peak current mode control with slope compensation.
The data sheet specifically indicates that current mode control with slope compensation…
Part Number: UCC3895 Other Parts Discussed in Thread: UC1875-SP OK, I understand; I'm straight now.
I'm only using the UCC3895 as it comes with a SPICE MODEL and it's a close cousin to the UC1875-SP, that has "NO" SPICE MODEL. I will eventually need…
Yes, this resolved my initial question. Yes, I am very aware of the UCC28951. I wish I could use it, unfortunately it does not come in SPACE GRADE. Also note, the UCC3895 is not SPACE GRADE. Fortunately the UC1875-SP is SPACE GRADE and is a very close…
Hey Terry,
It sounds like you are trying to create a phase shifted full bridge.
Have you considered the UC1875-SP?
This would allow you to control the dead time between switching.
Thanks,
Daniel
Other Parts Discussed in Thread: UC1875 I am trying to make a DC DC converter. 36v DC TO 300V DC using uc1875 ZVT PS TOPOLOGY.
uc1875 giving clean waveform when it is working alone with 12v supply and taking 40mA of current
when all the output (OUTA,B…
