LM3444 Datasheet - Texas Instruments

LM3444 AC-DC Offline LED Driver

The LM3444 is an adaptive constant off-time AC/DC buck (step-down) constant current controller that provides a constant current for illuminating high power LEDs. The high-frequency capable architecture allows the use of small external passive components. A passive PFC circuit ensures good power fact.

LM3444 Features

* 1 Application Voltage Range: 80 VAC to 277 VAC

* Capable of Controlling LED Currents Greater than 1 A

* Adjustable Switching Frequency

* Low Quiescent Current

* Adaptive Programmable Off-Time Allows for Constant Ripple Current

* Thermal Shutdown
