AN56581 - PowerPSoC® – Designing LED Driver Circuits for MR-16 Lamps with DMX-512 Interface
AN56581 describes the design of an LED driver circuit in a MR-16 form factor with DMX-512 interface using PowerPSoC controllers. This document demonstrates the use of PowerPSoC to design small form factor fixtures such as MR-16 lamps with DMX-512 interface. It outlines the architecture of the fixture and the LED driver board reference design, followed by its bring up and operation procedure. Code examples to implement color mixing for multicolor lamps and tunable white light systems are also provided.
The document describes a standard MR16 lamp with integrated LED driver. It gives an overview of the PowerPSoC family of controllers, specifications of the device used in this solution and a brief introduction to the DMX-512 communication protocol.
PowerPSoC product family provides a highly integrated platform for designing intelligent LED driver circuits that can be used in small form factors such as MR-16. This application note describes the design of a DMX512-enabled LED driver circuit for MR-16 using PowerPSoC. The application note also gives a top level description of the MR-16 fixture and the LED driver board reference design. It also briefly explains the board bring up and operation procedure. The application has an associated code example, which has sample firmware for multicolor lamps and tunable white light systems with DMX512 interface using PowerPSoC. A brief descirpion of the code example is also included in the applicaiton note.
