The INK1105 is a high-precision, multi-functional LED driver chip that provides a single-channel constant current output. The current output range is 5~500mA, and the current value can be set via an external resistor (RFB). The chip's operating voltage range is 2.1~5.5V. With a current setting voltage as low as 150mV and a low saturation voltage drop driving stage of 200mV, the INK1105 can provide a stable current output over a wide driving voltage range. The INK1105 requires few external components and offers good application reliability. The chip includes a high-precision bandgap reference source, a 5.5V voltage regulator, an over-temperature protection circuit, a low-dropout driver circuit, an active reverse protection circuit, and a drive mode control circuit. The INK1105 is a multi-functional LED driver. The FS0 and FS1 pins allow the IC to be set to different operating modes to meet various user application needs, supporting multiple operating modes: Automatic Power Control (APC), Automatic Current Control (ACC), and strobe mode. The INK1105 uses a small DFN8-2X2 package and has an operating temperature range of -40~125°C, complying with RoHS directives.
