LED DRVR 22V 14-Pin SO T/R

The SSTL21101T is a Switch Mode Power Supply (SMPS) driver IC. It is designed to drive LED devices typically in flyback configurations. The device includes a high-voltage power switch and a circuit enabling start-up directly from the rectified mains voltage. It has accurate control of the output current.
