Figure 3 shows the increase of the trigger current when
the device is expected to operate at an ambient temper-
ature below 25°C. Multiply the normalized I

Phase Control Considerations
LED Trigger Current versus PW (normalized)
Random Phase Triac drivers are designed to be phase
controllable. They may be triggered at any phase angle
within the AC sine wave. Phase control may be accom-
plished by an AC line zero cross detector and a variable
pulse delay generator which is synchronized to the zero

microprocessor which is synchronized to the AC zero
crossing. The phase controlled trigger current may be a
very short pulse which saves energy delivered to the
input LED. LED trigger pulse currents shorter than 100µs
must have an increased amplitude as shown on Figure 4.
