TPS54332: Alternative with greater input voltage and same functionalities

Riccardo Villani

Part Number: TPS54332
Other Parts Discussed in Thread: LMR14030, LMR16030

Hi All,

I'm looking for a buck converter same as the TPS54332 in terms of package and frequency but with a maximum input voltage of at least 42V. In other words, a TPS54332 with Vin_max >= 42V

Many thanks

Hi Riccardo,

You can check LMR14030.

Hi Vincent,

from the datasheet I see the LMR14030 has a Vin range from 4V to 40V (absolute maximum rate of 44V).

It might be good.

Could you suggest me also another p/n with same functionalities but Vin_max > 42V ? I mean Vin_max>42V in the input range without considering the absolute maximum rate.

In this way I will propose both solutions to the customer.

If you would like to take this offline let me know.

Many thanks

Riccardo

Hi Riccardo,

You can try LMR16030, whcih is a 60V part. Please contact wide vin for the recommendation as well.
