New from Texas Instruments is the TMS320C2000 Piccolo microcontroller (MCU) DC/DC LED developer’s kit.
The new LED controller kit enables developers to leverage the performance of low-cost Piccolo MCUs to differentiate LED designs with advanced features such as dimming, colour tone adjustment, power line communication and fault detection. Additionally, developers can reduce system cost through the integrated control of LED and power stages using a single Piccolo MCU.
The kit is adaptable for varying design needs, as it supports multiple power configuration options, modular Piccolo controlCARDs and a detachable LED panel. It comes complete with all of the open source hardware and software needed to jumpstart design of energy-efficient LED electronics, including backlighting, street lighting and building automation lighting.
The Piccolo F28035 controlCARD provides 60 MHz of 32-bit performance, 14 PWM outputs, a 12-bit, 4,6 MSps ADC, and 128 KB of Flash memory to support advanced lighting features. The digitally controlled buck/boost DC/DC 12-24 V power conversion stage allows developers to adjust voltage to match varying LED configurations. Eight independent 5 W LED strings allow unique current sensing for features like individual brightness adjustment and blown string detection.
