Part Number: LMR51440 Other Parts Discussed in Thread: LMR51430 Tool/software: Dear Specialists,
My customer is considering LMR51440 and LMR51430.
They have a question about the Vf of low side FET and rise/fall time of the FET.
I would be grateful…
Part Number: LM5119 Other Parts Discussed in Thread: PMP10260 , PMP20818 , CSD18534Q5A Hi,
It is said that Synchronous Buck "Freewheel" FETs must have Qgd/Qgs <1?
As such, please advise why ti.com has two reference designs of synch bucks, which violate…
Part Number: LM5143 Other Parts Discussed in Thread: PMP31210 , LM5119 , LM5148 , LM5146 , LM5145 Hi, do you know why the LM5143 (Synch Buck controller) was used for this Synch Buck spec (PMP31210 ref design) of 20-58vin and 13.5Vout and 50A out?... PMP31210…
Part Number: LM5145 Other Parts Discussed in Thread: , LM25145 , LM5146 Hi,
On the LM5145 product page both tools are listed. The Excel sheet looks similar, same input boxes. But when filling the sheets with the same requirements and values, I get large…
Hi Team,
buck converter without sync mosfet (conventional buck converter) any application note or any schematic avalible for high side floted mosfet driving perpose.
Part Number: BQ25756 Hi,
We have previously made some queries. The case number was CS2169510. Since it was closed, I am writing my next query as follos:
To reduce the Power Loss, we are more inclined to use GAN FET. Our selected component is EPC23102ENGRT…
Part Number: LM25149 Other Parts Discussed in Thread: CSD18540Q5B , LM5149 , , LM5149-Q1EVM-400 , LM5148 I'm working a design with the LM25149 with Vin = 36V (nom) Vout = 12V @ 15A max load.
Webench generates a design at Fsw = 250 kHz using CSD18540Q5B…
Part Number: CC3235SF Hi TI engineer
In my CC3235SF device,there have a fatal error :FATAL ERROR: Sync loss detected ,And MAP_PRCMMCUReset(1) can't reset device.
What should i do to restart system? And what cause this problem？
Part Number: UCD3138
I first created a DPWM module with a period value of 2.5us and set it to the normal closed-loop mode. After I used Front end2 as the Ramp source of my DPWM module, I enabled the SyncFET Ramp operation of the DPWM module. I find…
Hello Thrinesh,
Thanks for your interest in TI FETs. TI has a number of Excel-based FET selection tools including a synchronous buck tool which can be downloaded at the link below. I have also taken the liberty to prefill the attached spreadsheet based…
