The output current can be preset through an external resistor. Moreover, the preset current of MBI5043 can be further programmed to 64 gain steps for LED global brightness adjustment. With Scrambled-PWM (S-PWM) technology, MBI5043 enhances Pulse Width Modulation by scrambling the “on” time into sev...
