Other Parts Discussed in Thread: UCC29002, , TPS40054, TPS40055, TPS40050, TPS40051, LM5143, LM25145
Hi Texas Instruments,
I would like to use the TPS40057 controller for my current project. This project must have a load sharing feature using this controller. I'm planning to use the UCC29002 to control the load sharing using the similar circuit given on figure 2 of SLUA311 application note. However, there is a statement in the application note that says "Load sharing multiple modules requires each individual module to start up into a pre-biased load and not sink current supplied by other modules supporting the output".
Based on the datasheet of TPS40057, it can source and sink with Vo prebias. Does that mean the TPS40057 is not suitable for load sharing application? The following descriptions are quite unclear for me, can you please help explain the following details?
• TPS40054 Source Only
• TPS40055 Source and Sink
• TPS40057 Source and Sink With VO Prebias
Thanks and regards,
Chester
