Brief Description
The KTD2026/7 are fully programmable, constant current
RGB or RGBW LED drivers with a flexible control interface.
The devices are ideally powered from one-cell lithiumion/
polymer, 3-cell NiCd/NiMH/Alkaline batteries, or
systems with 3.3V or 5V supplies. The independent
programmable constant current sinks operate without
external components.
With an on-chip timing control unit, LED blink rate, fade-in
and fade-out are user-adjustable resulting in unique color
lighting patterns.
Ten internal registers are programmed via the I2C interface
with a built-in decoder allowing individual control of the
three/four LED channels’ On/Off state and current level. A
total of 192 current levels are available for each channel
from 0.125mA to 24mA with a 0.125mA step.
In shutdown mode, the quiescent current is reduced to less
than 1μA.
The driver is available in a low profile 8-pin 1.5mm x 1.5mm
x 0.5mm Ultra-Thin DFN package. The packages are Pbfree,
RoHS and Green compliant.
