Brief Description
The KTD2061/58/59/60 are fully programmable current
regulators for up to 12 RGB LED modules (36 LEDs
total). The devices are ideally powered from a supply
rail in the 3V to 5V nominal range. Three 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 on one I2C bus, the KTD2061/58/59/60
have different slave addresses.
36 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 ultrasmooth
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 KTD2061/58/59/60 are packaged in RoHS and
Green compliant 3mm x 3mm UQFN packages with
0.58mm maximum height.
