Part Number: UC1825-SP Other Parts Discussed in Thread: TIDA-00181 , LM5030 Tool/software: Hello, I would like to design an open loop fixed duty push-pull converter (no output inductor) using UC1825-SP.
Something like described in TIDA-00181 for LM5030…
Hi Dylan!
Thanks so much for taking the time to get in touch. The LM5030 device can control a push-pull converter under open loop conditions as long as a pre-regulated input signal is provided. A great example can be found in the TIDA-00181 TI reference…
Hello,
What are the currents on each rail? Do you want to generate each rail using separate LM5030 device? +/-100 can be generated using LM5030 but for +/-5V and 1.8V, any buck converter can be used (Example is given in schematic of TIDA-01352)
LM5030…
Mohsen,
See below for recommendations to your query:
1) is that fine to use only three isolated dc/dc converters, one for each phase? I mean is it fine to supply the low side gate drivers directly without any isolations? I guess i should be fine.…
Hi Bell,
The UCC2897A does not support hiccup mode operation so I would recommend to consider the LM5025 or LM5026 as alternate if you perfer the Forward topology. But I think maybe push-pull would be a better choice as you can take advantage of the…
Hi Lakshmi,
Thanks for sharing this diagram. After interfacing with some of my coworkers, we'd like to recommend looking into LM5030, used as an open loop push pull supply. You can see this device used in the TIDA-00181 reference design, generating…
