Product Introduction

peculiarity

Application voltage range 80V AC - 277V AC It is capable of controlling LED currents greater than 1A Adjustable switching frequency Low quiescent current Adaptive programmable shutdown time allows for constant ripple current Thermal shutdown No 120Hz flickering Low-profile 10-pin MSOP package Patented drive architecture

illustrate

The LM3444 is an adaptive, constant shutdown time AC/DC step-down (step-down) constant current controller that provides a constant current for high-power LEDs for illumination. High frequency capability architecture that allows the use of small external passive components. Passive PFC circuitry ensures a good power factor, plots directly from the current cycle line, and provides a constant positive voltage buck regulator. Additional features include thermal shutdown, current limiting, and V CC undervoltage lockout. The LM3444 is a low-profile MSOP-10 package.
