KTD2052B: 12-Channel RGB LED Driver with I2C Control and integral fade-engines

“Using multiplexing techniques, the number of PCB traces can be reduced by a factor of 3, significantly reducing the solution size over competing solutions.”
— Jia Hu, Kinetic Technologies’ Senior Director of ESIA Product Marketing

SAN JOSE, CALIFORNIA, UNITED STATES, January 11, 2021 /EINPresswire.com/ -- Power management and video/audio interface leader, Kinetic Technologies, is adding to its innovative line of RGB LED drivers with the introduction of the KTD2052B a 12-channel fully programmable current regulator capable of driving up to four RGB LEDs with fewer PCB traces. Packaged in a tiny 8-pin UDFN package, the KTD2052B is 2x smaller than competing products.

“The KTD2052B is ideal for driving up to 4 RGB LEDs in A.I. Speakers, IoT, Gaming Controllers or V.R. Headsets”, says Jia Hu, Kinetic Technologies’ Senior Director of ESIA Product Marketing. “Using multiplexing techniques, the number of PCB traces can be reduced by a factor of 3, significantly reducing the solution size over competing solutions. To help simplify software design and to reduce the burden on system resources, a flexible pattern generator allows set-and-forget autonomous useful patterns. In systems with long boot times, or long periods of inactivity, the RGB LEDs will ‘AutoBreathe’ blue light, showing the user the system is alive”.

Programmed by a 1MHz, I2C serial interface, the KTD2052B has an integrated pattern/animation engine that controls 12 independent current sinks with, in NORMAL-mode, up to 24mA/LED in 125µA steps and in NIGHT-mode, up to 1.5mA/LED in 8µA steps. A 3-bit programmable fade-rate with ultra-smooth 8µA steps is also included. Optimized for the lowest power consumption, the KTD2052B also includes Kinetic’s patented BrightExtend™ and CoolExtend™ technologies preserving color balance and the ability to maintain light output at high operating temperatures. In case of LED failure (Shorts, Open, Dropout) additional protection and monitoring functions are included.

Key applications for the new KTD2052B include A.I. Speakers, Bluetooth / WiFi Loudspeakers, automotive indicator and ambiance lighting, IoT, gaming consoles and controllers, toys, indicator / button illumination.

The KTD2052B is available with an alternative I2C address option to double the number of RGBs in a system and is available without AutoBreathe. All options are shipping now.
