.. a1780 general 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 indication for protection function Ambient temperature range 0°C to 70°C Package: Die-in-waffle-pack or SOP14 example application schematic
