TPS650231: Lower voltage support

Part Number: TPS650231

Hello TI team,

We have the below list of power rails for our device where we are planning to use the PMIC for our application.

0.9V - 1.8W
1.8V - 0.6W
3.3V - 0.2W
1.5V - 0.5W

We found that we are unable to generate the 0.9V using this PMIC.

Let us know how we can do the same.

If needed what will be the alternate solution

Hi Pratik,

Just to be clear, this PMIC is capable of generating 0.9V but there are only 3 DCDC regulators so are you saying that you need another solution because this device doesn't have enough BUCK rails?

Regards,

James

Hello James,

We can use other LDOs for the remaining power rails.

Do you have any better solutions compared to this one.

Hi Pratik,

The LP87564-Q1 might be an option for you. It has 4 DCDC regulators with a minimum VOUT of 0.6V.
