  • RE: LM25145: LM25145RGYR FB regulation voltage level

    Understood.

  • RE: LM25145: FET operation problem

    Hi Minsu, Using an external wire to power the gate drive will provide much worse performance. In order to properly change the routing of the gate drive signals, there would need to be a revision in your board's layout. Please do so following above recommendations…

  • LM25145: schematic check request

    Part Number: LM25145 Other Parts Discussed in Thread: LM5146-Q1 Tool/software: Hi Sir, after comparing it with LM5146-Q1 EVM board, it seems that there is no problem, could help confirm it again for suggest where need to modify it? thanks for you help…

  • RE: LM25145: LM25145 output voltage is not changing 2.6V,

    Yes, they are pin to pin compatible so you should be able to drop the LM25145 right on the board. Webench is auto generated so I would be more inclined to use the EVM. Regards, Rahil

  • LM25145: Is there harm to controller if output is powered by another source when controller is disabled?

    TI Thinks Resolved
    Part Number: LM25145 Tool/software: I would like to disable the buck controller when voltage drops to a certain level and bypass the buck regulator by connecting the input voltage to the buck regulator output. Will this cause any harm to the controller…

  • RE: LM25145: output DC voltage with programmable step output like 0V ,4V ,8V,16V ,20,24v

    Resolved
    Hi Sagar, What's "DC-C"? You mean DC/DC... See Fig. 10 here https://www.ti.com/lit/an/slyt777/slyt777.pdf These circuits generally apply to any buck regulator with a FB pin. Note the LM25145 also has a tracking input, which allows manipulation…

  • LM25145: Disable overcurrent protection

    TI Thinks Resolved
    Part Number: LM25145 Tool/software: Hi Team, Our customer would like to know how to disable the current limit function of the LM25145. Please see the details of his inquiry below. During actual operation, the RILIM value calculated by the RILIM calculation…

  • LM25145: Webench simulations 'failing' for certain input requirements?

    Part Number: LM25145 Other Parts Discussed in Thread: LM61460 Tool/software: I'm trying to design a voltage converter to go from 28V to 24V at a max of 4A (everything else default) and while checking out the LM25145, I noticed that the simulations showed…

  • LM25145: Seeking Recommendations for Voltage Mode DC-DC IC for 40-50A Output Current at 1.6V

    TI Thinks Resolved
    Part Number: LM25145 Other Parts Discussed in Thread: TPS549D22 , TPS53819A , LM25143 Tool/software: I have designed a power supply using the LM25145 , which operates with an input voltage range of 8V to 32V and delivers a constant output voltage of 1.…
