OFF-LINE SWITCHING REGULATORS – WITH BIPOLAR SWITCHING TRANSISTOR

The STR-S6703 and STR-S6704 are specifically designed to meet the requirement for increased integration and reliability in off-line quasiresonant flyback converters. These devices incorporate the primary control and proportional drive circuit with a third-generation high-voltage bipolar switching transistor.

FEATURES
■ Quasi-Resonant Operation for Low EMI and High Efficiency
■ Output Power to 140 W
■ Low-Power Output Standby Mode
■ Pulse-by-Pulse Over-Current Protection
■ Latched Over-Voltage and Thermal Protection
■ Third-Generation Switching Transistor with Proportional Drive
■ Maximum ON Time and OFF Time Set During Manufacture
■ Internal Under-Voltage Lockout with Hysteresis
■ Over-Molded SIP with Integral Isolated Heat Spreader
