For proper operation, the minimum input voltage must
always be:
where V
connected LEDs. The minimum operating voltage of the
device is +6.5V. The device operates below +6.5V; how-
ever, output current may not meet the full regulation
specification.
The MAX16836 provides pulsed or chopped current
dimming input (DIM). The other method is to connect
DIM to V5 and EN to IN and pulse EN. Both methods
generate a regulated-amplitude PWM current (variable
duty cycle) that can provide control over the LED
brightness (see Figures 1 and 2).
