Overview

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. QR operation, when selected, occurs at heavy load and is achieved through a transformer demagnetization sensing input that triggers MOSFET turn-on. Under some conditions, ZVS (zero-voltage switching) can be achieved. The converter’s power capability rise with the mains voltage is compensated by line voltage feedforward. At medium and light load, as the QR operating frequency equals the oscillator frequency, a function (valley skipping) is activated to prevent further frequency rise and keep the operation as close to ZVS as possible.
