Description

R2A20134ASP is a LED lighting controller IC.

Control method is a fixed frequency mode.

Error Amp Mode realizes High Power Factor and High Efficiency.

And the Peak Current Mode makes it possible to reduce external parts and realize low system cost.

The Error amp Mode control output current and the Peak Current Mode control output power.
