With a 40V rated integrated switch FET, the CXLE8192 is a boost converter that drives LEDs in series. The boost converter runs at 600kHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows for the use of small external components.The default white LED current is set with the external sensor resistor R_SET, and the feedback voltage is regulated to 200mV, as shown in the typical application. During the operation, the LED current can be controlled using PWM signal through the CTRL pin. The duty cycle of pulse width modulation (PWM) signal determines the feedback reference voltage. In PWM mode, the CXLE8192 does not burst the LED current; therefore, it does not generate audible noises on the output capacitor. For maximum protection, the device features integrated open LED protection that disables the CXLE8192 to prevent the output voltage from exceeding the IC’s absolute maximum voltage ratings during open LED conditions.The CXLE8192 is available in Green TDFN-2×2-6L and TSOT-23-6 packages. It operates over an ambient temperature range of -40℃ to +85℃.
