TIDA-03027: Board Design with USB PD and 1x USB 2.0 Port

Part Number: TIDA-03027

We are looking to develop a solution that does the following:

 

There would essentially be two conditions:

Condition/Case 1:

The device is not being charged but has a USB 2.0 device attached. In this case the USB 2.0 device would be powered and communicate with the phone directly.

 

Condition/Case 2:

In this case a USB Power Delivery Charger is connected to charge the phone.

When the charger is connected, the phone still needs to be able to access the USB 2.0 device, we can power the USB 2.0 device using a DC-DC converter to drop the incoming voltage to 5V.

 

My query is which IC is suitable for this?

 

The most promising option that I found was the evaluation board TIDA-03027. What I would like to know is if this is the best option or if there is a simpler option available considering my requirement.

    I am clear on why the TPS65987D is a good fit.

    Could you please help me out with the controller used in the TIDA-03027 evaluation module as I cannot seem to find it in the Schematic diagram.

    Hi Emil,

    The TIDA-03027 does not have a controller. The configurations on the PD controllers is enough to met the requirements of that design without requiring a controller.

    Thanks,
    Eric
