Part Number: LM62435-Q1

Hi,

I am planning to use "LM62435-Q1" for converting 24VDC to 5V, 3A.

5V is supplied to external components (Load cell) using a connector, in industrial environment.

5V@3A supply should be stable as this is the important requirement for our customer.

Is "LM62435-Q1" part is suitable for the above purpose? If not please suggest me which part goes well with the requirement.

Thanks,

Dinesh KS

    Yes, this device is suitable.

    Ensure you operate at appropriate frequency for board condition and desired losses, but you might want to consider the adjustable frequency variant LM61435.

    On a lot of typical application boards, 25degC/W-30degC/W board rtheta can be obtain without too much effort.

    With determine loss, and estimated board rtheta, estimated junction can be calculated

    tj = tamb + board rtheta * loss
