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