CCG3PA Power Adapter/Car Charger (1C+1A) single chip solution hardware design tips

CCG3PA Power Adapter/Car Charger reference design in Type-C reference designs (LINK: https://www.cypress.com/products/usb-type-c-and-power-delivery ) is below structure as per the reference design name and link.

1. CCG3PA Car Charger Reference Design using Southchip (https://www.cypress.com/documentation/reference-designs/ccg3pa-car-charger-reference-design-using-so... )

The hardware block diagram is below:

2. EZ-PD™ CCG3PA USB-C PPS 39W Dual Port Car Charger (Power Adapter) Reference Design (https://www.cypress.com/documentation/reference-designs/ez-pd-ccg3pa-usb-c-pps-39w-dual-port-car-cha...​)

The hardware block diagram is below:

3. EZ-PD™ CCG3PA USB-C Mobile Power Adapter Solution using Power Integrations (https://www.cypress.com/documentation/reference-designs/ez-pd-ccg3pa-usb-c-mobile-power-adapter-solu... )

The hardware block diagram is below:

4. EZ-PD™ CCG3PA USB-C Mobile Power Adapter Solution using Diodes (https://www.cypress.com/documentation/reference-designs/ez-pd-ccg3pa-usb-c-mobile-power-adapter-solu... )

The hardware block diagram is below:

5. 45W EZ-PD™ CCG3PA USB-C Notebook Power Adapter Solution using MPS (https://www.cypress.com/documentation/reference-designs/45w-ez-pd-ccg3pa-usb-c-notebook-power-adapte... )

The hardware block diagram is below:

From all of block diagram, the design is demonstrating each port (either Type-C or Type-C) have dedicated DC/DC convector or AC/DC convector. If you are looking for a single DC/DC convector or AC/DC convector designed to service Type-C and Type-C port. Below block diagram could be refer to. This design could be easy to achieve based on above reference design.

Notes:

1) VBUS_IN_DIS and VBUS_C_MON can be exchanged.

2) The VBUS enable sequence is supported by dynamically, the priority of Type-C or Type-A shall be defined before firmware customize. (This is trade off the BOM cost down).

3) Need additional Type-A detach/attach circuits for Type-A port. If the detach/attach circuits is composed by Amplifier, the current detect accuracy shall be consideration (50mA as minimum recommend).

4) CCG3PA is looking for Vfb=1.2V.
