Product Summary
The L6565N is a current-mode primary controller IC, specifically designed to build offline Quasi-resonant ZVS (Zero Voltage Switching at switch turn-on) flyback converters. Quasi-resonant operation is achieved by means of a transformer demagnetization sensing input that triggers MOSFET’s turn-on. The applications of the L6565N include TV/monitor SMPS, AC-DC adapters/chargers, digital consumer and printers, fax machines, photocopiers and scanners.
Parametrics
L6565N absolute maximum ratings: (1)IVcc, ICC + IZ: 30 mA; (2)IGD, Output Totem Pole Peak Current (2 μs): ±700 mA; (3)INV, COMP, VFF, CS, Analog Inputs & Outputs: -0.3 to 7 V; (4)IZCD, Zero Current Detector 50 (source): -10 (sink)mA; (5)Ptot, Power Dissipation @Tamb = 50℃ (Minidip): 1W; (SO8): 0.65W; (6)Tj, Junction Temperature Operating range: -40 to 150℃; (7)Tstg, Storage Temperature: -55 to 150℃.
