Brief Description

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, ultra-thin, 20-pin UQFN
package.
