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
