I'm looking at a 100W USB PD application, derived from on the 4531 CCG3 EVK hardware.

What firmware constants, variables, or definitions should I change to allow up to 5A current output capability?

Hi Ray,

Based on CY4531 hardware, and CYPD3125-notebook firmware, you shall change below items based on your requirements.

1. Make sure the power input of NCP1034 have enough power watt.

2. Change config table of CYPD3125 by EZ-PD configuration Utility. This can be completed by USB to mini-B and connect to CY4531 board. Main change is Source PDO of CYPD3125.

Best Regards,

Lisa
