To minimize voltage drop and maximize efficiency, the value of the internal current sense resistors connected in series with the LEDs is very low This is an important consideration for direct DC-driven white LEDs in battery-powered systems. The LED current can be set to 0mA OFF Mode , 7mA, 14mA, and 21mA with a built-in, two-bit, digital-toanalog converter. Customized current settings can also be used. When the control bits are set to zero, the internal circuitry is disabled and the quiescent current drops below 1µA. Both digital input lines A, B can be pulse-widthmodulated PWM .
