Part Number: TPS53319

Hi TI Team,

I want to confirm the connection setting for TPS53319 FCCM mode.

In the datasheet it says it should be connected to PGOOD pin, but didnt mention to pull it up with VREG.

The circuit for EVB shows it is pull up with 100kohm to VREG.

So is the connection in EVB correct?

Thanks

Hi,

You can refer to table 3, it is connected to PGOOD for FCCMM and also remark (1) under the table is helpful to understand. and actually the EVM is also connect to PGOOD, and PGOOD is pull-up with Vreg5.
