This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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 Features

  • include the addition of an internal start-up circuit eliminating bulky external components while allowing independent boost converter operation. Addition of internal current sense blanking eliminating the need for an external R/C filter network. Internal clamping of the error amplifier and multiplier outputs improves turn on overshoot characteristics and current limiting. Special circuitry has also been added to prevent no load runaway conditions. And finally, output drive clamps limiting power.
