The CXLE8188 is a versatile constant current LED driver with a high efficiency step-up converter architecture. Unique technology and high 1.35A current limit allow CXLE8188 to drive up to 38V output (10 LEDs in series). Alternatively, CXLE8188 can deliver 260mA total current with 3 series LEDs per string. It can also maximize the current capability while achieving high conversion efficiency. The optimized 1MHz switching frequency results in reduced conduction loss and small external component size. A single wire interface is integrated to adjust the FB voltage in 32 steps, which can overcome audible noise and inrush current issues in normal PWM dimming schemes.Various protection features are built into the CXLE8188, including cycle-by-cycle input current limit protection, open LED (output over-voltage) protection and thermal shutdown protection. The leakage current in shutdown mode is less than 1μA.The CXLE8188 is available in Green TSOT-23-6 package. It operates over an ambient temperature range of -40℃ to +85℃.
