Descriptions
The KTD2064 is a fully programmable current regulator for up to 8 RGB LED modules (24 LEDs total). The device is ideally powered from a supply rail in the 3V to 5V nominal range. Two 4-wire buses are multiplexed to reduce the pin-count and PCB traces to the LEDs.
The I2C control interface is used to set the LED color palette and then dynamically select the on/off status and color of each RGB module. For applications requiring more RGBs, see the KTD2061/58/59/60.
24 independent fade-up/down engines are integrated for independent ramping of each LED’s current during on/off, brightness, and color transitions without software burden. The exponential current ramps provide visually pleasing fades with eight I2C programmable fade-rate settings. 3072-step fade resolution ensures ultra-smooth visual effects.
BrightExtend™ optionally reduces dropout when the input voltage is too low for the forward voltage of the LEDs, enabling battery-powered applications. Programmable CoolExtend™ prevents excessive heat by regulating die temperature when the input voltage, current settings, and/or ambient temperature are high.
The KTD2064 is packaged in RoHS and Green compliant 3mm x 3mm UQFN packages with 0.58mm maximum height.
