Part Number: LM5119 Other Parts Discussed in Thread: PMP30464 , , LM5149 Tool/software: Hi Team,
This is Gree FAE Ryker. Recently Gree wants to find a high-power BUCK as below request. I have promoted LM5119 and reference design PMP30464 firstly. But Gree…
Part Number: LM5119 Tool/software: Hi TI expert
I found the application report ZHCA658 from TI website to study the RC snubber circuit design.
In the section 1.3, it gives the formula of the equivalent circuit[figure 3], and the selection guide of the…
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…
Part Number: LM5119 Hi!
I have recently finished a schematic for a LM5119 Dual Output design. I was hoping to have it reviewed to see if any parts of the design need to be changed. Attached is the schematic. I used the LM(2)5119 Calculator to get most…
Part Number: LM5119 I recently got an LM5119 evaluation board and have been happy with the performance so far. I have an application that would require two 40V, 10A outputs and this part seems like a perfect fit. However, one thing I have noticed in the…
Mahmoud Harmouch said: It seems the issue is related to ramp optimization. When you changed VIN, the sub-harmonic is worse at lower input voltage because the duty cycle is higher. Higher duty cycle needs more attention to slope compensation. I understood…
Part Number: LM25119 Other Parts Discussed in Thread: LM5119 , Team,
I am looking at possibly using LM25119 as a replacement for LM5119. Looked through the datasheet for any major differences, but they look to be about the same.
But wanted a quick sanity…

Part Number: LM25119 Other Parts Discussed in Thread: LM5117 , LM5119 , LM25117 , We have been using the LM5119 and also a LM5117 on our products.
We find it easier to obtain the LM25119 and LM25117 parts at present.
The boards are nominally 24VDC.
The higher…
Part Number: LM5119 Hi, TI expert.
The customer has an inquiry about UVLO operation of LM5119.
- Condition : When forced UVLO off, UVLO off after 321ms Delay by external circuit.
- Questions)
Low Side FET operates intermittently under the condition that…
