Hi,

I am currently looking for a power supply/adapter and was considering the EZ-PD™ CCG3PA. I would like to incorporate the power block into the reference design. The project has a small form factor (6in dia), will be plug-in, and last 10yrs. The power requirements for the design are as follows:

  • Component 1: Voltage 5V, Current:2A
  • Cellular Device: Voltage 3.3~3.8V (typical), 4.3 max, Current 1.8a(typical) 2A(max)
  • LED Strip:2/3.2/3.2V(typical),2.6/4/4V (max) per section, Current 0.02A per section or 7.2 A in total
  • Speaker: Voltage 12v(min), 28V (max), Current 13mA

The maximum power consumption by my calculations should be 57.824 W with a total maximum current 11.028 A and the highest voltage being 28V.

Do you think this power delivery design will work? Do you have any better recommendations For the project?

Thanks

Hi ,

Based on Type-C power delivery can support up to 100W (20V/5A), it could work with Cypress solution design.

1. For Component 1: Voltage 5V, Current:2A requirements, Type-C power delivery can use fixed PDO with 5V/2A to meet the requirements.

2. For LED Strip: 2/3.2/3.2V(typical),2.6/4/4V (max) per section, Current 0.02A per section or 7.2 A in total, Type-C power delivery can use PPS with 3.3V - 5.9V @ 200mA to meet those requirements.

3. For Speaker: Voltage 12v(min), 28V (max), Current 13mA, Type-C power delivery can use PPS with 3.3V - 21V @ 13mA to meet those requirements. 21-28V cannot achieve it with Type-C power delivery, but it is can use Alt mode to achieve it.

Anyway, Type-C Power Delivery is power SPEC. the requirements can be powered with single solution power supply whatever the power sink requirements is same or difference.

Best Regards,

Lisa

Hi,

Thanks for answering me! I was wondering would the same still apply if the 110/120V AC input (what is supplied to a commercial residence/wall outlet)?
