R2A20134SP Block Diagram
説明
R2A20134SP is an LED lighting controller IC. The control method is selectable for each system demand, fixed frequency, or zero current detection mode. A high-accuracy LED current feedback system makes LED performance more efficient. Critical Conduction Mode PFC control realizes a high power factor and zero current switching. And, Peak Current Mode makes it possible to reduce external parts and realize a low system cost.
