High-Voltage, 350mA, High-Brightness LED
Driver with PWM Dimming and 5V Regulator
Input-Voltage Considerations
For proper operation, the minimum input voltage must
always be:
V IN(MIN) ≥ V SENSE(MAX) + V FT(MAX) + ? V DO(MAX)
where V FT(MAX) is the total forward voltage of all series
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
Paralleling Multiple MAX16836s
to Drive One High-Power LED
For applications that require more than 350mA of LED
current, two or more MAX16836s can be paralleled
(see Figure 3). V CS - should not exceed 4.1V.
specification.

R1
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).
