The VAS1106 is a constant current controller designed to be compatible with triac dimmers. A string of series/parallel LEDs is tapped at three locations, three integrated high voltage switches track the input sine wave voltage and turn on/off automatically. Voltage across each switch is minimized when conducting, providing high efficiency. The VAS1106 includes a bleeder circuit to ensure proper triac operation by allowing current flow while the line voltage is low to enable proper firing of the triac. An input voltage detecting circuit ensures high efficiency by shutting down bleeder current when voltage is high enough to hold the triac operating. VAS1106 is available in a SOP8-e package
