UL22 controller equivalent, led driver controller.
It includes a cycle-by-cycle current limit to the power switch; over-current protection at the LED load; bias voltage VDD over-voltage protection. In addition, the drive.
UTC UL22 provides several protection features. It includes a cycle-by-cycle current limit to the power switch; over-cur.
Featured Device, UTC UL22, is a PWM controller with innovative Free-DimmingTM technology. The controller drives one of the two strings of LEDs by an ON/OFF AC wall switch and provides a cost effective solution for light control. It supports power-fac.
