GENERAL DESCRIPTION
: The frequency (offtime) can be programmed using a single resistor. The LED string is driven at constant current rather than constant voltage, thus providing constant light output and enhanced reliability. The output current can be programmed between a few milliamps and up to more than 1.0A. The FT6610 uses a rugged high voltage junction isolated process that can withstand an input voltage surge of up to 450V.
