Nordic Semiconductor’s new nRF51 series of wireless devices can implement Bluetooth low energy, ANT+ or proprietary wireless applications using an embedded ARM 32-bit Cortex-M0.

As more applications continue to integrate LED technology, developers face the challenge of driving greater numbers of LEDs while lowering system cost and increasing power efficiency. For systems requiring multiple strings of LEDs, TI provides two example solutions illustrating differing power stage topology designs and digital control methods. This whitepaper explores the different LED driver topologies and digital control methods available for driving multiple LED strings efficiently to reduce system cost, lower operating expenses, increase color accuracy, and improve overall reliability.
