摘要：CXLE8184 supports up to 6 white LEDs and regulates a constant current which the initial value can be set by an internal resistor. The part implements PWM dimming to adjust the brightness of LED. User

The CXLE8184 is a high performance white LED driver. It integrates current sources and automatic mode selection charge pump. The part maintains the high efficiency by utilizing a 1×/1.5× fractional charge pump and low dropout current sources. The small equivalent 1× mode open loop resistance and ultra-low dropout voltage of current source extend the operating time of 1× mode and optimize the efficiency of Li-ion battery in white LED applications.IvW嘉泰姆

The CXLE8184 supports up to 6 white LEDs and regulates a constant current which the initial value can be set by an internal resistor. The part implements PWM dimming to adjust the brightness of LED. Users can easily configure the LED current from 0mA to 27mA by a digital PWM signal. CXLE8184 can be turned off by EN pin. The operating voltage range is 2.7V to 5.5V. Internal soft-start circuitry effectively reduces the in-rush current while both start-up and mode transition.IvW嘉泰姆
