SP6300 Datasheet | Kodenshi AUK Group

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 pensated 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 pliant. Features - Flyback Operation with Quasi-Resonant Soft Switching for Low Power Dissipation and EMI - Temperature-pensated 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.
