UL24U
DESCRIPTION
Featured Device, UTC UL24U, is a PWM controller with innovative technology. The controller drives a strings of LEDs and can be dimming by an ON/OFF AC wall switch and provides a cost effective solution for light control. It supports power-factor-correction function in applications.
UTC UL24U provides several protection features
. It includes a cycle-by-cycle current limit to the power switch; over-current protection at the LED load; VDD over-voltage protection. The controller also features an internal over-temperature protection.
