While developments in LED technology are there for all to see, less attention has been paid to the technology of LED driving. In fact, techniques for implementing LED control have changed in recent years. These changes have been spurred by the development of advanced mixed-signal semiconductor manufacturing processes which enable the production of ‘smart’ LED drivers: these integrate digital control functionality with analog power circuitry in a single, low-cost chip. This paper examines how the use of this new generation of smart LED drivers can deliver improved low-power LED performance while reducing system power consumption.
