Mfr. Part No. KIT_LED_XMC1202_AS_01
As part of an impressive increase in their combined Infineon and International Rectifier stocked range, RS has introduced this easy-to-use RGB LED lighting shield which has also been designed to provide options for the evaluation of smooth, easy on the eye dimming, and colour mixing for different topologies. It can be extended with for example DALI/DMX or radar.
The board offers a comprehensive LED diming solution in that it is easy to use, but for advanced users and parameterization, provides backdoor access to on-board-microcontroller. In addition its small footprint delivers flexibility for size constrained applications, thanks to high-frequency current control achieving high power density.
The RGB LED lighting shield is one of the first intelligent evaluation boards compatible with Arduino Uno R3 as well as Infineon’s XMC1200 BOOT KIT, meaning flexibility in adapting to wider or pre-existing system solutions.
It is designed to be easy to configure and suitable for different LED engines and lamps, for fast prototyping and in-expensive evaluation of LED lighting applications.
The RGB LED Lighting Shield uses a DC/DC buck converter and is able to drive up to 3 LED channels with constant current. The shield itself is powered by an on-board XMC1202 microcontroller, XMC 32-bit ARM® MCU with embedded Brightness Colour Control Unit (BCCU, XMC1200 MCU series), to achieve true flicker-free LED dimming and colour control.
The BCCU enables extremely low-cost but high quality LED lighting solutions, with minimal user software input, saving time to market, and bringing LED lighting into lower cost market spaces.
Summary of Features:
- Easily configurable for various light engines and any input voltage (within operating conditions)
- Wide DC input voltage range
- Simple I 2C interface
- Fast design start using Infineon’s downloadable software and tools, boot kits, and other associated LED lighting dev kit (see below).
- Fast prototyping of LED lighting
- Flicker-free light thanks to high-speed pulse density modulation
- Easy-to-use dynamic dimming and colour control
