TPS659037: 1.1V RTC supply

Shanu V

Part Number: TPS659037

Hi,

I am working on SoC development for tablet PCs.

The SoC RTC supply voltage requirement is 1.1V

TPS659037 matches the current requirement, but doesn't have 1.1V RTC supply.

Is there any PMIC from ti which has RTC supply voltage of 1.1V?

    Hi Shanu,

    I couldn't find any devices in our portfolio with 1.1V RTC supply. Most have 1.8V or 3.3V for RTC LDO.

    One idea is to add an external LDO from LDOVRTC_OUT to your 1.1V RTC domain. Then this 1.1V RTC rail will always be on when the PMIC is powered and LDOVRTC_OUT is on, but you will get the correct voltage you need.

    Regards,
