Other Parts Discussed in Thread: TPS650250

Our customer has been considering TPS650250.
In case of not using DCDC3, they will connect the pins related DCDC3 to GND.

Are there anything concern?

Best regards.

Hi,

If you are not using DCDC3, it is recommended to connect the following pins in the following way:
1.EN = GND*
2.VINDCDC3 = VINDCDC1 = VINDCDC2 = VCC*
3.L3 = Float
4.VDCDC3 = GND
5.DEFDCDC3 = GND
6.PGND3 = GND*

* = MUST
