Texas Instruments today announced its new TMS320C2000 Piccolo microcontroller (MCU) DC/DC LED Developer's Kit. The kit enables developers to incorporate Piccolo MCUs to differentiate LED designs with features such as dimming, color tone adjustment, power line communication and fault detection. Additionally, developers can achieve the integrated control of LED and power stages using a single Piccolo MCU. The kit is adaptable for varying design needs, because it supports multiple power configuration options, modular Piccolo controlCARDs and a detachable LED panel. The DC/DC LED Developer's Kit 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 MCU DC/DC LED Developer’s Kit (TMDSDCDCLEDKIT) features a Piccolo F28035 controlCARD which provides 60M Hz of 32-bit performance, 14 PWM outputs, a 12 bit, 4.6 megasample per second ADC, and 128 KB of flash memory; digitally controlled buck/boost DC/DC 12 V to 24 V power conversion stage allows developers to adjust voltage to match varying LED configurations; and eight independent 5 W LED strings allow unique current sensing for features like individual brightness adjustment and blown string detection.
