The CC1108 is a high-precision linear LED driver chip that provides a single-channel constant current output. The output current range is 5~200mA, adjustable via an external resistor (RFB). The chip's operating voltage range is 2.5~24V. A low current setting voltage of only 150mV and a low saturation voltage drop driving stage of 200mV allow the CC1108 to provide a stable current output over a wide driving voltage range. The CC1108 requires few external components and offers high application reliability. The chip includes a high-precision bandgap reference source, a 5V voltage regulator, an over-temperature protection circuit, a low-voltage difference drive circuit, and a low-offset high-precision amplifier. The CC1108 has a built-in intelligent over-temperature protection function, preventing flickering during over-temperature protection. The chip's internal temperature sensor detects the CC1108's temperature status; when the internal temperature exceeds 110℃, the over-temperature protection circuit activates, and the temperature-controlled PWM circuit adjusts the output duty cycle of the drive. This signal's duty cycle decreases as the temperature rises. When the chip junction temperature exceeds 150°C, the duty cycle is reduced to 0, and the output is completely shut off. The CC1108 uses a small SOT23-5 package and complies with RoHS directives.
