Description
General part information
L6566A Series
The L6566A is an extremely versatile current-mode primary controller IC specifically designed for high-performance offline flyback converters operated from front-end power factor correction (PFC) stages in applications in compliance with EN61000-3-2 or JEITA-MITI regulations.
Both fixed-frequency (FF) and quasi-resonant (QR) operation are supported. The user can choose either of the two depending on application needs.
The device features an externally programmable oscillator; it defines the converter's switching frequency in FF mode and the maximum allowed switching frequency in QR mode.
