Description of reference design

Dimming interface
For more advanced applications, the reference design also includes an interface for
dimming. The board itself does not include any signal generator, but to keep universality
with different control schemes (analog or digital dimming) a three-pin connector was built in
as depicted in
generator (implemented by either the microcontroller or by comparators). The PWM pin is
an universal dimming input, working with both analog and digital dimming. Any voltage
above 2.5 V is considered as 0% power, i.e. the analog dimming works in the range from
0 V to 2.5 V, where 0 V (grounding the pin) results in full power. The standard 3.3 V logic
levels can be used as a PWM control signal for digital dimming. In this case the brightness
changes from 0% (full power) to 99% (minimum power) duty cycle. If the driver is used
without the PWM generator, pins 1 (GND) and 2 (PWM) on the PWM connector must be
connected together.
