LMR51430: LMR51430 to replace TPS563252

Lillian Liu(SH)

Part Number: LMR51430
Other Parts Discussed in Thread: TPS563252,

Hi team,

Schneider encountered a problem in IC selection and would like to inquire whether LMR51430 can be used instead of TPS563252.

The application is to power radio frequency devices, which has relatively high requirements on ripple and response speed.

Input 10V, output 3.8V, transient is responsible for 0.1A to 2A, Drop is not lower than 3.3V, recovery time is about 4ms

The main reason is that LMR51430 DS does not indicate that it can be used in radio frequency applications, so I am not sure， could you help check for this?

...

Thanks

Lillian

Hi Lilian,

I think LMR51430 can meet customer needs. They can also use our EVM to evaluated. Thanks.

Hi Aurora,

Thanks for your reply.

Could you provide some simulation result support? Or provide PSPICE model?

Thanks

Lillian

Hi Lillian,

We currently do not have a pspice model and they customer can use Webench simulation. Customers can test the our EVM by themselves. If you need us to help with testing, you can send me an email (aurora-tie@ti.com). We can provide the test results next week. Thanks.
