Brief Description
The KTD2042 is an ideal power solution for RGBW LED
driver with an integrated buck regulator. It has 9 highprecision
current sinks that can be independently
controlled via I2C interface.
The buck regulator has an input voltage operating range
from 2.7V to 5.5V to accommodate 1-cell lithium-ion
batteries or 5V voltage rail. It has adaptive output
voltage control based on the headroom voltages of the
LED current sinks to minimize the power consumption.
has integrated high-side and low-side power FET. The
buck regulator features advanced adaptive On-Time
control with 1MHz switching frequency, which minimizes
external component counts and allows the use of a very
small inductor and capacitor.
The KTD2042 has 9 built-in current sinks, which features
independent On/Off control and 6-bit independent
current dimming via I2C interface. The KTD2042 has
extensive built-in protection features including cycle-bycycle
current limit, input undervoltage Lockout (UVLO),
output over-voltage protection, LED fault (open)
protection and thermal shutdown protection.
The KTD2042 is available in a RoHS and Green
compliant 3mm x 3mm UQFN package.
