The CXLE8187 is a versatile constant current LED driver with a high efficiency step-up converter architecture. The low-side power MOSFET is integrated in the device, significantly shrinking the overall PCB layout area and minimizing the total number of external components. Unique technology and high 1.6A current limit allow CXLE8187 to drive up to 38V output (10 LEDs in series). Alternatively, CXLE8187 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 600kHz switching frequency results in reduced conduction loss and small external component size. Digital PWM dimming interface is integrated to adjust LED current. The PWM frequency is in the range from 2kHz to 60kHz.Various protection features are built into the CXLE8187, 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 CXLE8187 is available in Green TSOT-23-6 package. It operates over an ambient temperature range of -40℃ to +85℃.
