    Hi,

    Currently we haven't defined the variant for AWRL6432 system requiring 5V. 

    There could be possibility of this but we do not have timeline yet.

    Hi, Ishtiaque,

    Thanks for your quick reply.

    I already review the OTP sheet of TPS65036502 & TPS65036503.

    I think TPS65036502 can be used for AWRL6432.. If I used TPS65036502 for AWRL6432, is there some risk?

    Please share the your opinion.

    Thanks,

    Hello Kim,

    Yes TPS65036502 can be used and only difference is the LDO is enabled where is in  TPS65036503 the LDO by default is disabled. 

    So the LDO will be redundant rail which would imply that they would have to have LDO 2.2µF input + output cap. However, customer can disable it once the device is powered up through I2C. Or they can make use of it for another peripheral if there is any possibility in the system.

    Hi Ishtiaque,

    Thanks for your reply.

    I am a little confused, because TPS65036502 has only one 3.3V rail. (LDO) Is it wrong?

    Please check again, anyway, TPS65036502 can be used with AWRL6432, right?

    Thanks,

    Yes TPS65036502 has one LDO which is configured as 3.3 V and it is enabled.

    Yes it can be used. But as I explained earlier  that TPS65036503  is defined for AWRL6432 with BUCK1 3.3V and BUCK2 1.8 and BUCK3 as 1.2V which is considered sufficient for the over all system power requirement and for that purpose LDO is disabled. 

    However, in your application if the 5V is required then yes TPS65036502 can be used.
