Datasheet Summary
No Input Electrolytic Capacitor Required, IEC61000-3-2 Class-C Isolated LED Driver IC
LC5546AD/LD
Data Sheet
Description
The LC5546AD and LC5546LD are isolated LED drivers in which a power MOSFET and a control IC are highly integrated.
The IC provides the systems that can ply 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.
