The LM3444MA/NOPB is an AC-DC offline LED driver designed for high-power LED applications. It operates within an input voltage range of 80 V_AC to 277 V_AC and is capable of controlling LED currents greater than 1 A. The device features an adaptive constant off-time control architecture, which allows for efficient operation with small external passive components. It includes a low quiescent current, thermal shutdown protection, and a current limit feature. The driver is available in a low-profile 10-pin VSSOP or an 8-lead SOIC package, making it suitable for various lighting applications, including residential, industrial, and commercial lighting. The LM3444 also ensures no flicker at 120 Hz and provides a good power factor through its passive PFC circuit.
