LMQ66410-Q1: Part Number Clarification

Cvetan Marinov

Part Number: LMQ66410-Q1
Other Parts Discussed in Thread: LMQ66430

Hello Dear TI Team,

Regarding the LMQ66410-Q1 device, according to its Data Sheet, SNVSC78B – FEBRUARY 2022 – REVISED MAY 2023, 5 Device Comparison Table on Page 3,

there is a device with 1A max. output current: LMQ66410R5RXBR.

However such Part Number cannot be identified and found anywhere, including on TI product site.

Could you please clarify whether part number LMQ66410R5RXBR is valid and active Part Number or we should focus on the other 5V/adj. Output Voltage devices such as LMQ66420R5RXBR and LMQ66430R5RXBR?

Best regards,

Hello

The Q grade 1A device should be on TI.com.

Please allow two days for the non-Q 1A device to appear on the web.

We have only very recently released that device.

Thanks

Hello Frank,

Thank you (as usual).

Well, on TI Website, under the Product Page of LMQ66410-Q1: https://www.ti.com/product/LMQ66410-Q1?keyMatch=LMQ66410-Q1&tisearch=search-everything&usecase=GPN, there is the 1A-rated AEC qualified device LMQ66410MC5RXBRQ1.

Obviously, part number LMQ66410R5RXBR is non-AEC qualified.

Additionally, is there Quickstart design tool for the LMQ664x0-Q1 devices?

Best regards,

Cvetan Marinov

Hello

It does not look like there is a quick start guide available for that device yet.

I will ask the team if they plan to create one.

Thanks

Hello Frank,

It is valuable and very convenient to use the quick start tool, so let us hope the Team is planning to create for the LMQ664x0 devices.

Thank you Frank!

Perhaps under some conditions Texas Instruments could create and validate a PSpice model for LMQ66410-Q1?

Dear Frank,

Thank you!

What is your opinion, in which case the available at TI.com samples of LMQ66410MC5RXBRQ1 could be delivered faster: to Japan or to Bulgaria?

Best regards,

Hello

I am not sure I can answer that question.

It may be faster going to Japan.

Thanks
