KP18069
KP18069 PF>0.7, Five-channel linear I2C dimming LED driver KP18069 is a high-precision RGB low-voltage CW high-voltage five-channel 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 analog and PWM dimming. Each channel supports 1024 grayscale dimming, meeting dimming requirements in various scenarios. The CW channel of KP18069 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 40V and a maximum current of 160mA, meeting the linear constant current requirements of low-voltage RGB. KP18069 features high constant current accuracy and 0.1% dimming depth. KP18069 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 will automatically reduce the output current to ensure system stability.
