Kinetic Technologies, a developer of high-performance analog power and protection semiconductors, will be showcasing the world’s smallest 36-channel RGB LED Driver at the upcoming CES 2019 event. The event is scheduled from January 8-11 in Las Vegas, Nevada.
Colored LED lighting has become ubiquitous in today’s lives ranging from RGB indicators on AI speakers to arrays of LEDs covering entire buildings. Kinetic Technologies has developed an innovative 36-channel RGB LED driver, the KTD2061, which dramatically reduces the design complexity and lowers the solution cost.
Traditional RGB drivers have one output pin per channel. This often requires large PCB routing spaces as well as expensive high density interconnect circuit boards. The KTD2061 uses a multiplexing technique known as Charlieplexing to control 36 output channels using only 12 pins, thus significantly reducing PCB routing and enabling the use of inexpensive two-layer PCBs. The patented BrightExtend technology enables battery operation by decreasing dropout when the input voltage is too low for the forward voltage of the LEDs. The CoolExtend feature prevents excessive heat when the input voltage, current settings, or ambient temperature exceeds programmable thresholds.
In addition, the KTD2061 is the first in the industry to integrate a hardware fade engine per channel. This exponentially reduces the amount of software commands traditionally required to implement a lighting pattern. According to Kinetic Technologies, the KTD2061 will free up a system’s MCU and the I2C bus, potentially even allowing customers to choose a lower-cost processor.
