... LED display with a constant voltage. According to the SEL pin status, the SP6415 either regulates output current flowing through series connected LEDs or regulates output volt- age applying to the OLED. A single external resistor is used to set the maximum LED current. The LED current can be adjusted by applying a PWM signal to the EN pin ...
