A1780 - Dimmer IC

Datasheet Summary

Features

The a1780 is a dimmer IC for halogen lamps. It uses an integrated time controller to control a wide range of DMOS switches, and includes protection circuits against overcurrent, over-voltage and over-temperature. 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 ind.
