Other Parts Discussed in Thread: TPS65400, AWR1243

Hi,

Is it appropriate to use TPS65400 instead of LP87524 to power AWR1243 ?

two LP87524 is needed to power four awr1243 chips,

instead,one TPS65400 and another Dc-Dc can meets the current requirement of four awr1243,should save PCB area and support 12V voltage supply:

What should I pay attention to when replacing LP87524 with TPS65400 and provide a clean power rail for RF chips?

Hi,
No technical content in the former reply,regardless of the awr1243,a simple performance comparison of the two chips（TPS65400 and LP87524）will do better.

Hello Min,
You can refer to the TPS65400 and LP87524 datasheets to compare the two. As mentioned in the other E2E thread (e2e.ti.com/.../755609) ,please contact local TI sales rep to get more details on our cascade solution.
