Introduction

AI Translation

CC1108 is a high- precision linear LED driver chip, which provides a single channel constant output current, with a current output range from 5mA to 200 mA. The current value can be set by external resistance (RFB). The operating voltage range is 2.5V - 24V. The low current setting voltage of 150mV and the low saturation voltage drop driving stage of 200mV enable CC1108 to provide stable current output in a wide driving voltage range. CC1108 requires few external components and has high application reliability. The chip contains high precision bandgap reference source, 5V voltage- regulator circuit, over- temperature protection circuit, low drop- out drive circuit, low offset and high precision amplifier.

CC1108 has built- in intelligent over- temperature protection function, and there is no strobe flash during over- temperature protection. The temperature sensor inside the chip can detect the temperature state of the CC1108; When the internal temperature of the CC1108 chip exceeds 110°C the over- temperature protection circuit will start, and the temperature control PWM circuit will adjust the output duty cycle of the drive. The duty cycle of this signal decreases with the increase of temperature. When the junction temperature of the chip exceeds 150°C the duty cycle decreases to 0 and the output is completely turn off.

CC1108 adopts SOT23- 5 small package. Comply with RoHS requirements.

Features

AI Translation
  • Vcc pin with the function of reverse connection protection, the reverse current does not exceed 10 uA. Effectively reduce the required external components.
  • Wide operating voltage range, VCC: 2.5V~24V
  • Strong driving ability, output continuous current up to 200mA
  • The feedback voltage is as low as 150 mV
  • The current has the function of temperature regulation: when the ambient temperature is too high, the output current decreases automatically
  • The quiescent current is low, only 500 uA, which helps to improve the luminous efficiency of lamps.
  • Minimum overdrive output voltage: VDRV - VFB: 0.2V@lou=200mA
  • Current mismatch between chips<4%@ lou=200mA
