Cxle86188a cxle86188b is a 2.5V ~ 40V wide input range, boost type white LED constant current driver chip, which can achieve 7W (7x1w) driving capacity under the input voltage of AC12V / DC12V. Cxle86188a cxle86188b adopts fixed working frequency and current mode to adjust LED current. The system has fast transient response, stable loop and simple design. Cxle86188a cxle86188b adopts high-level current detection technology, which can set the average working current of led through external resistance. 205mv low reference voltage effectively reduces power loss and improves efficiency. 460khz fixed working frequency minimizes external inductance, input and output capacitance. Cxle86188a cxle86188b supports PWM dimming and analog dimming through a single control pin. The chip includes over-voltage protection (OVP), over-current protection (OCP), over temperature protection (OTP) and other protection mechanisms to ensure the safe and reliable operation of the system.
