Description
General part information
L6566BH Series
The L6566BH is an extremely versatile current-mode primary controller IC, specifically designed for high-performance offline flyback converters running off rectified 3-phase input lines. It is also suited to single-stage, single-switch, input-current-shaping converters (single-stage PFC) for applications that must comply 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 switching frequency in FF mode and the maximum allowed switching frequency in QR mode.
When FF operation is selected, the ICs work as a standard current-mode controller with a maximum duty cycle limited to 70% min. The oscillator frequency can be modulated to mitigate EMI emissions.
