Texas Instruments Inc. has introduced a wireless remote control LED design kit. The TPS62260LED board plus the eZ430-RF2500 development tool completes a fully supported platform to design color lighting innovations for consumer, commercial, professional and architectural applications.

Opening up new possibilities for low-power lighting design, the TPS62260LED board controls the color and brightness of a lamp or runs an automatic color light animation program. Designers generate color with the three OSRAM high-brightness LEDs (red, green and blue). An MSP430F2131 ultra-low power MCU controls the brightness of each LED with constant current generated by three TPS62260 LED drivers, one for each LED.

The design module is also pin compatible with TI's TPS62240 buck converters for lower-current LED applications, such as indoor ambient lighting, and the TPS62290 for higher-current LED applications, such as wall washing.

Wireless control
Designers can utilize wireless communication by using the eZ430-RF2500 development tool, which plugs directly onto the TPS62260LED board. This allows designers to create a lighting network of RF-controlled lamps. With an RF remote, the need for additional infrastructure to control the lamp is eliminated. Utilization of RF lighting control allows for better management of LED lamp-lighting intensity and color. RF remote-controlled lighting is beneficial in applications like building automation control networks because it allows for upgrading facilities to LED lighting with minimal wiring infrastructure changes.

Pricing and availability
The TPS62260LED board is available today at a suggested resale price of $19 and includes a populated and pre-programmed MSP430 MCU, plus board documentation. Additionally, the eZ430-RF2500 development tool can be ordered for $49. If a designer prefers to reprogram the MSP430, a separate MSP430 Flash Emulation Tool can be ordered, such as the MSP-FET430UIF Development Tool, which has a suggested resale price of $99.
