KP18068
KP18068 PF>0.7, Five-channel high-voltage linear LED dimming chip KP18068 is a high-precision five-channel high-voltage LED linear constant current dimming chip that meets the requirements of IEC-61000-3-2:2020. The current of the 5 channels can be independently set via the I2C (Inter-Integrated-Circuit Bus) interface, supporting various dimming modes. The CW channel uses analog dimming, while the RGB channels support both analog and PWM dimming. Each channel supports 1024 grayscale dimming, meeting the dimming requirements of various applications. The CW channel of KP18068 has a withstand voltage of 500V and can be directly powered by AC input to drive high-voltage light strips, with a maximum current of 77.5mA; the RGB channels have a withstand voltage of 500V and a maximum current of 48mA, meeting the requirements of high-voltage RGB linear constant current. KP18068 features high constant current accuracy and 0.1% dimming depth. KP18068 integrates a line voltage compensation function, with selectable compensation points and slopes, easily meeting high and low voltage constant power requirements without additional components. It also integrates an over-temperature protection function. When the chip temperature exceeds the over-temperature protection point, the chip automatically reduces the output current to ensure system stability.
