JP1 - EXTERNAL PWMD CONTROL INPUT
Connecting the PWMD pin to VDD enables
the converter. Applying a PWM TTL signal
between the PWMD pin and GND adjusts the
average output current to the LEDs according
to the duty cycle.
LD MONITOR
The LD pin is connected to
the wiper of RA1. LED current
may be reduced in a linear
fashion by adjusting RA1.
