Note 1: All devices are 100% production tested at T A = +25°C. Limits over the operating temperature range are guaranteed by design.
Note 2: LED current sink dropout voltage is defined as the voltage at which current drops 10% from the current level measured at 0.6V.
Note 3: Flash duration is from rising edge of FLEN until I FLED turns off (or returns to the movie current setting if MVON is high).
Note 4: The MAX8830 step-up converter IN supply current is tested in an open-loop configuration with no inductor. Actual closed-
loop IN supply current is higher due to conduction losses in the inductor and LX nFET and pFET. These additional losses are
highly dependent on inductor value and series resistance.
