| Description | 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-factor-correction function in applications. UTC UL22 provides several protection features. It includes a cycle-by-cycle current limit to the power switch... |
| Features |
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 driver output (DRV) voltage is clamped for driving the external power MOSFET effectively and safely. The controller also features an internal over-temperature protection.
