Application Information (continued)

PWM Dimming

The AL5809 can be used to provide LED current dimming driving the Out pin via the MOSFET switch to ground (Figure 4a) applying a PWM

signal with a frequency range between 100Hz and 200Hz. The Out pin current is then effectively switched on and off to modulate the output LED

current. The dimming effect can be achieved by varying the PWM signal duty cycle.

Test conditions (Figure 4a): PWM frequency 100Hz–200Hz Square wave, 0-4V gate voltage, VIN = 6V, 1 LED, AL5809-30mA

Use the following formula to calculate the Min and Max duty cycle:

Min. Duty cycle (%) = (t_{ON_MIN}) / (time period of the PWM signal)

Max. Duty cycle (%) = 100% - ((t_{OFF_MIN}) / (time period of the PWM signal))

Notes: t_{ON_MIN}= 0.5mS (Min. value), and t_{OFF_MIN}= 0.5mS (Min. value) are listed in the Electrical Characteristics table on page 4.
