LM53603: out of stock - recommendations for drop-in alternatives?

Sebastien Arnoux

Part Number: LM53603
Other Parts Discussed in Thread: LMR33630, , LMR51430

To whom it may concern, my company uses TI part LM53603AMPWPR (or WPT suffix) to generate a 5 V supply for a load of up to 2.6 A and another almost identical circuit on the same PCA, to generate a 3.3 V supply for a load of up to 3 A.

This part is out of stock at the moment.

Other than the automotive version (LM53603-Q1 which is also out of stock), can you please recommend any drop in alternatives in an HTSSOP 16 package.

Note, I have looked at the LM63635DQPWPRQ1 and it is almost a drop-in replacement, but it is also out of stock.

Kind regards,

-Sebastien A.

Hi,

I have checked with our team that there is currently no pin-to-pin or TSSOP 16 package that can replace the LM53603. We suggest that you can try to contact local suppliers or other channels to purchase. Or you can choose to replace chips in other packages(like LMR51430 LMR33630). LM53603 is currently out of stock. we're sorry about that.

Best Regards,

Aurora
