KP18026
KP18026 High-efficiency, dual-channel dimming and color temperature adjustment linear constant current LED driver KP18026 is a dual-channel dimming and color temperature adjustment linear constant current driver chip. The new Link-Dim® technology builds an adaptive high PF LED driver architecture. The front-end uses a high PF adaptive constant voltage control buck converter, and the rear-end uses KP18026 to achieve constant output current, dimming control, and feedback of LED voltage to adjust the appropriate output voltage of the front-end. It features low system cost, high efficiency, and output without low-frequency ripple. KP18026 has two independent channels of PWM dimming function, supporting dimming and color temperature adjustment. Each channel can achieve a dimming range of 1%~99%, and achieve a dimming accuracy of ±10% at minimum dimming, ensuring good color consistency of the light source in the entire dimming range. KP18026 integrates LED open circuit protection, LED short circuit protection, and over-temperature protection functions. In addition, in order to protect against LED exceeding the rated current due to accidental short circuit of the RISET resistor, KP18026 also integrates ISET short circuit protection to reduce the output current to the minimum dimming state. These protections ensure the safety and reliability of the system.
