The L6565 features a current mode control and is designed for flyback converters working in
quasi-resonant mode and ZVS (zero voltage switching) at turn-on, or at least quasi ZVS,
which means valley switching during turn-on. This condition allows the designer to reduce
the power losses at turn-on as much as possible.
Since the input range is from 250 V up to 850 V, the ZVS is obtained only when

The L6565 has 8 pins. For a detailed explanation of each pin function, please refer to the
