Hi Sir,

My customer looking for video conference application solutions.

System power comes from Adapter, no battery, but have a USB C connector, need support USBC charging out

  1. Two USB Type C output
    1.   USB Type C1 output only support 5V/3A, 9V/3A, 15V/3A, 20V/3.25A (65W Max.)
    2.   USB Type C2 output only support 5V/3A, 9V/3A, 12V/2.5A, 15V/2A, 20V/1.5A (30W Max.)
    3.   USB Type C1 output + USB Type C2 output = 45W + 18W
  2. Use case: Device doubles as a Type-C charger for your laptop or phone
  3. USB Type C2 support data transceiver. 
  4. Device doubles as a Type-C charger for your laptop or phone
  5. support QC (option) => system platform is Qualcomm QCS825
  6. no battery, but need support charging out.

 Q:

1. USBC charging out (output:5V/3A, 9V/3A, 15V/3A, 20V/3.25A) solution

TPS65987D + TPS55288 is good solution? Or others comments.

 2. Do we have Headset ALT mode switch + codec solution?

Thanks, Ian.
