The LM3528 is a current mode boost converter offering two separate outputs. The first output (MAIN) is a constant current sink for driving series white LEDs. The second output (SUB/FB) is configurable as a constant current sink for series white LED bias, or as a feedback pin to set a constant output voltage for powering OLED panels. It features an I2C compatible interface for independent adjustment of LED current in 128 exponential steps and includes a programmable pattern generator for indicator functions.
