Kinetic Technologies' presents the KTD2042, a highly versatile power solution for RGBW LED drivers featuring an integrated buck regulator. This compact device is available in a RoHS compliant 3 mm x 3 mm UQFN package, ensuring compatibility with environmentally friendly regulations.
The KTD2042 is equipped with nine high-precision current sinks that can be independently controlled using on/off signals and 6-bit independent current dimming through an I²C interface. This level of control allows for precise adjustment of individual LED colors.
The buck regulator within the KTD2042 operates within an input voltage range of 2.7 V to 5.5 V, accommodating both 1-cell lithium-ion batteries and 5 V voltage rails. It employs adaptive output voltage control based on the headroom voltages of the LED current sinks, effectively reducing power consumption.
Featuring integrated high-side/low-side power FETs, the buck regulator ensures efficient power delivery. Its advanced adaptive on-time control with a 1 MHz switching frequency minimizes the need for external components, allowing for the use of smaller inductors and capacitors.
The KTD2042 incorporates a range of built-in protection features including cycle-by-cycle current limit, input undervoltage lockout (UVLO), output overvoltage protection, LED fault (open) protection, and thermal shutdown protection. These safeguards ensure the safe and reliable operation of the device and protect against potential failures.
Overall, the KTD2042 from Kinetic Technologies provides a compact and efficient solution for RGBW LED drivers. With its high-precision current sinks, adaptive output voltage control, and comprehensive protection features, it is well-suited for a wide range of lighting applications.
