LX1562IDM

The LX1562 is a second-generation family of power factor correction controllers using a discontinuous mode of operation.
They are optimized for electronic ballast applications. Many improvements have been made over the original SG3561A controller introduced by Silicon General Semiconductor in 1992.KEY
