Part Number: LM4755

Hi,

some time ago the LM4755TS was set to obsolete Status.

Now ist is again available under LM4755TSX/NOB.

We odered some samples for evaluation but they are branded with National Logo not TI.

Can you confirn that LM4755TSX will be availabe for some years with new production charges

or ship you old stock material from National up it is outsold.

We need this information for planning obsolete development.

Thank in advance.

Greetings

Hi Steffen,

Welcome to E2E, thanks for your interest in our devices.
I think you are confused. Only the TO-220 Package of this device was set to obsolete status and we are not planning to set obsolete status the TO-263 package (LM4755TSX/NOPB).

Hi José Luis,

Thanks for the Information.

I was a little bit confused because I have ordered samples of LM4755TSX in TO-263 and

I became LM4755TS in TO-263 with National Logo.

Can you confirm that the real TI LM4755TSX will be 100 percent parameter compatible to the

formerly National chip LM4755TS.

Best regards

S. Simon

Hi Steffen,

We can only guarantee that IC belongs to Texas Instruments if It was bought directly or an official distributor.
Where did you buy the ICs?

Hi ,

i orderd the samples over the official TI sample Service, but inside National chips

That the originial National chip works is clear.

Are the TI chips the same under our Label?

Hi Steffen,

You can be sure that the device will be working well since you ordered them from TI sample service.
