AWR1642: AWR1642ABISABLQ1 1.7V power consumption

Hello Bonnie,
The 1.7V rail is used on the secure variant of the AWR1642 device ONLY during the period of flashing the customer encryption keys. So this could just a pin where the 1.7V is supplied during production. The LDO on the EVM was put only for ease of our development.

Hi Vivek,

We're trying to find another TI LDO to replace the original EVM design (TPS79601DRB)
We need to know the maximum current that VPP would drain and then decide which LDO is better.
Unfortunately, there's no VPP characteristic description in datasheet nor TRM.

BTW, can we use 1.8V for VPP? This could reduce BOM further.

Hi Vivek,
Thanks for your replying. we know this power just use on DL code stage.
Can you still help to provide the power consumption(mA) for this power rail?
We want to select a lower current LDO.

Beset Regards,
Chris Lin
