1，Refer to AWR2243BOOST，is the LP87524-Q1 designed for AWR2243 matching?

or a more appropriate recommendation？

2，About LP87524-Q1

LP87524-Q1‘s OTP files, Can LP87524-Q1 directly output the first off voltage?
If IIC is not configured, and the EN pin is pulled high. Can LP87524-Q1 directly voltage output ?

Hello Delmore,

Yes LP87524J-Q1 is specifically intended for radar applications and it has default output voltages and sequencing to support AWR. See detail on the default setup here: https://www.ti.com/lit/ug/snvu663a/snvu663a.pdf

You don't need I2C to enable bucks with their default voltages, setting EN1 pin high is enough.

Thanks.

Regards,
