TPS650331-Q1: Will need to look for the PMIC to support LP5 (PMIC5200)

QX Lee

Part Number: TPS650331-Q1

Tool/software:

I would like to get support to have PMIC to supply for LP5 (PMIC5200), the detail is as below:

Reason to have 2 PMIC solution is due to the board space

PMIC 1	Buck out 1 = 1.05V
	Buck out 2 =0.5V
	LDO out = 1.8V
PMIC 2	Buck out 1 =1.8V
	Buck out 2 =0.9V
	LDO out = 1.0 V

Hi Phil:

Actually on the current design we are using the MPS part MP5424

But due to the board constrain, we would like to find the smaller PMIC, so that to spread the power to 2 PMIC

Hi QX,

We have TPS6593-Q1 and TPS6594-Q1 PMICs; they're very similar with the MPS part MP5424. Using those PN in e2e title for related Apps sup[port.

Thanks!
