Tool/software:

Hello

I am planning to design a radar using multiple AWR2243s.
If I use two AWR2243s, I need one PMIC, and if I use four AWR2243s, I need two PMICs,
but if I use three AWR2243s, how many PMICs will I need?

Regards
Tsuda

    Hi Tsuda,

    I believe you are talking about the LP87524-Q1 PMIC for this application. It seem like for three AWR2243s you would still need 2 PMICs. In the cascade radar EVM they have 4 radars and two PMICs like you said and each PMIC powers the RF rail for two radars and then it powers the digital core rail and analog/digital rail for both radars. 

    regards,

    Niko
