LED DRIVER CONTROLLER
DESCRIPTION
Featured Device, UTC UL24D, 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 UL24D provides several protection features. It includes a
cycle-by-cycle current limit to the power switch; over-current
protection at the LED load; V DD over-voltage protection. The
controller also features an internal over-temperature protection.
FEATURES
* Using ON/OFF wall switch to dimming
* High power factor for high brightness LEDs
* Low start-up current and operating current
* Under-voltage lockout (UVLO) with hysteresis
* Provides complete protection functions
