The CXLE8103 is a continuous mode inductive step down converter. It can driving single or multiple series connected LEDs. The CXLE8103 includes the output switch and a high-side output current sensing circuit, which use an external resistor to set the average output current. Output current can also be adjusted by applying an external signal to the ‘ADJ’ pin. The ADJ pin will accept either a DC voltage or a PWM waveform. The PWM filter components are contained within the chip. Applying a voltage under 0.2V to the ADJ pin will turn off the output.
