The STR-S6525 is specifically designed to meet the requirement for increased integration and reliability in off-line flyback converters operating in a constant OFF-time mode. The device incorporates the primary control and drive circuit with a discrete avalanche-rated high voltage power MOSFET.

FEATURES
■ Constant OFF-Time Converter Operating Mode
■ Avalanche-Rated Power MOSFET Switch
■ Pulse-by-Pulse Current Limiting
■ Latched Over-Voltage and Thermal Protection
■ Maximum ON Time and OFF Time Set During Manufacture
■ Internal Under-Voltage Lockout with Hysteresis
■ Over-Molded SIP with Integral Isolated Heat Spreader
■ External Synchronization Capability
