QX6 103 is a high-precision buck high-power LED constant-current driver chip. The output current can reach more than 3A. The chip adopts patented high-end current detection and constant frequency and constant current mode PWM control mode, which has excellent linear regulation rate and load regulation rate. The chip has built-in frequency compensation and slope compensation without external compensation. QX6 103 also integrates the frequency jitter function to improve the EMI characteristics of the system. QX6 103 integrates various protection functions, including LED short-circuit protection, cycle-by-cycle limit current protection, input power under-voltage protection and power clamping.
