PWM dimmer function
LED current can be adjusted according to Duty of PWM pulse input to PWM dimmer pin. PWM pulse is High (2V to
5V) then switching operation stops, and LED current stops flowing. PWM pulse is Low (under 0.6V), then switching
operation stop is released, and it returns to normal operation.

PWM_D
Threshold voltage, 1.5V (typ).
(note) at PWM_D pin, input voltage is,
2V avove - output OFF
0.6V below - output ON
