Dimming Output Current Using PWM
When the ADJ pin is driven with a low frequency PWM signal (eg 100Hz), with a high level voltage V
and a low level of zero,
ADJ
the output current will be switched on and off at the PWM frequency, resulting in an average output current I
proportional
OUTavg
to the PWM duty cycle. (See Figure 2)

PWM dimming is preferable to DC dimming if optimum LED 'whiteness' is required. It will also provide the widest possible
dimming range (approx. 1000:1) and higher efficiency at the expense of greater output ripple.
