Overview
No Input Electrolytic Capacitor Required, IEC61000-3-2 Class-C Isolated LED Driver IC LC5540LD Series Data Sheet Description The LC5540LD series are isolated LED drivers in which a power MOSFET and a control IC are highly integrated.
The IC provides the systems that can comply with the harmonics standard (IEC61000-3-2 Class C) in all conditions, including a light load condition.
These systems, moreover, can be achieved without an input electrolytic capacitor.
The IC employs the average current and quasi-resonant controls: the average current control realizes high power factors, whereas the quasi-resonant control contributes to high efficiency and low noise.
Having a rich set of protection features, the IC can provide and more cost-effective power supply systems with fewer external components.
Features ● Built-in On-time Control Circuit (High Power Factor Achieved by Average Current Control) ● Built-in Startup Circuit (Reduced Numnber of External Components) ● Soft Start Function (Sta...
