SP6300

www.DataSheet4U.com Semiconductor SP6300 Quasi-Resonance Flyback Controller Description The SP6300 is specifically designed to satisfy the requirements for increased Integration and reliability in 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 Converter's power capability variations with the mains voltage are compensated by line voltage feedforward. At light load the device features a special function that automatically lowers the operating frequency still maintaining the operation as close to ZVS as possible. In addition to very low start-up and quiescent currents, this feature helps keep low the consumption from the mains at light load and be Blue Angel and Energy Star compliant. Features Flyback Operation with Quasi-Resonant Soft Switching for Low Power Dissipation and EMI Temperature-Compensated Pulse-by-pulse Over-Current Protection Latched Over-Voltage and Thermal Protection Under-Voltage Lockout with Hysteresis Active Low-Pass Filter for Enhanced Light-Load Stability Regulated Soft Gate Drive Applications TV/MONITOR SMPS DIGITAL CONSUMER AC-DC ADAPTERS/CHARGERS PRINTERS, FAX MACHINES, PHOTOCOPIERS AND SCANNERS Ordering Information Type NO.
