2.10 Linear Dimming
A linear dimming function can be implemented by
applying a DC control voltage to the LD pin. By varying
this voltage from 0V to V CS(high) , the user can adjust
the current level in the LEDs which in turn will increase
or decrease the light intensity. The control voltage to
the LD pin can be generated from an external voltage
divider network from V DD . This function is useful if the

user requires LED current of a particular level, and
there is no exact R T value available. N ote that applying
a voltage higher than the current sense threshold
voltage to the LD pin will not change the output current
due to the fixed internal threshold setting. When the
LD pin is not used, it should be connected to V DD .

Pulse width modulation dimming can be implemented
by driving the PWMD pin with a low frequency square
wave signal in the range of a few hundred Hertz. The
PWMD signal controls the LED brightness by gating
the PWM gate driver output pin GATE. The signal can
be generated by a microcontroller or a pulse generator
with a duty cycle proportional to the amount of desired
light output.
