CYPRESS SEMICONDUCTOR AN15733 Power Management - RGB Color Mixing Hardware For EZ-Color LED Controllers handbook
This application note (AN15733) explains how to drive multiple high‑power LEDs using Cypress EZ‑Color devices such as the CY8CLED16. It covers temperature‑feedback and color‑sensor feedback loops, constant‑current driver topologies, and practical design considerations for the CY3261A‑RGB demonstration board.
The document includes two PSoC Express example projects that demonstrate LED dimming, color mixing with PrISM blocks, and I²C‑controlled tuning. It also provides a brief appendix of photometry units and author contact information.
