Part Number: LM5176

Hi Team,

We want to use LM5176 to design for large watt load, condition is
  Vin 9~36V to 12V output 400w

I saw a file sharing between two parallel four-switch with droop method for higher power.



Can share provide this schematic & BOM ?

thanks

Kevin

  • Hi Kevin,

    Thanks for considering the usage of the LM5176 in your design. In the application note attached, this was implemented by simply tying the two outputs of the LM5176EVM together with an external circuitry using two INA194. 

    There is another variant that utilizes a single op-amp seen here: http://www.ti.com/lit/an/snva826/snva826.pdf

    In either case, there is no available BOM noted here, since all this requires is a small external circuit that utilizes a few resistors and capacitors. There are component parameters included in the application note which you can use to design your external circuit.  

    Thanks,

    Richard
