LM48511: LM48511 Rdson

Richard Elmquist

Part Number: LM48511

This question has been asked in the forum, but was not answered. Since this value is not easy to calculate from the dissipation numbers can you supply this? It is called for in many calculations throughout the data sheet.

Thanks for your help with this!

Richard,

I have been searching the data, but I haven't been able to find it. It is quite difficult to find this kind of information as this device is very old. Unfortunately, people who worked with this device are not longer on TI.

Jose,

Is the information unavailable?

I understand if it unavailable, but please let me know .

If it is unavailable, how should the customer do the calculations that include Rdson? Can he use a standard value? Please give me an idea of how the customer could do the calculations without the Rdson value.

Thanks for your help with this!

Richard,

I have calculated the output impedance that should be a value very approximate to Rdson, and I got Rout = 190mΩ.
