a1780 general features The a1780 is a dimmer IC for halogen lamps. A LED gives a visual indication of the output status at all times.
● Dimming range: between 10% and 95%
● Flexible soft start function (hot and cold – soft start)
● Zero-crossing detection
● Protection function for over-current, over-voltage and over-temperature
● LED status indication for protection function
● Ambient temperature range 0°C to 70°C
