Other Parts Discussed in Thread: CSD18533Q5A , LM25118 , CSD16415Q5 Hi, we are a couple of students designing a power for our ECU project.
We've made a design in webench using the LM25118 Buck/Boost controller, which implements both the CSD18533Q5A…
Your block diagram season reasonable and we have no current plans for EOL of the bq24133 in the near future.
For questions regrading the LM25118, please post to the appropriate forum for the best support.
Thanks,
Rachel
Looks like LM5118 or LM25118 are the closest choices. They are not synchronous however. There is also an integrated synchronous solution, TPS55065-Q1. Output current is limited since the FETs are internal.
Hello Akshay,
Thanks for the hints. I am also considering using the buck-boost LM25118/LM5118 instead of LM3481, since it needs just one inductor, this helps to save a lot of space on the pcb.
Beyond the large inductor to guarantee the CCM mode…
Other Parts Discussed in Thread: LM25118-Q1 I need a dual supply solution with the following specs:
8 - 75V input
2 outputs:
non-isolated 12V 20mA
isolated 12V 50mA
Automotive rated
Small as possible
low-cost (of course)
I am…
Hi,
Please find below our actual scenario:
1) VCC_BAT is our input voltage point. We are powering the Buck/Boost converter (LM25118) with 12V input and found LM25118 generating 5V.
2) Our Input voltage range is 3.6V to 12V. We are initially powering…
Steven,
Your post has two different parts in it with two different designs and several different questions. Are you using the LM25118-Q1 or the LM5085-Q1?
Its been a year since I began my Lithium battery control board using the BQ24630 combined with a LM25118 Buck boost converter . I got it thru some QA, ESD RFI, and abuse testing with little if no failures, but only after multiple iterations.
Some things…
