STR-S6513 OFF-LINE SWITCHING REGULATOR - WITH POWER MOSFET OUTPUT DRAIN 1 OSC. FAULT LATCH Data Sheet 28102.10 SOURCE R MON OVER-CURRENT PROTECTION V IN The STR-S6513 is specifically designed to meet the requirement for increased integration and reliability in off-line flyback converters operating in the quasi-resonant ringing choke mode. The device incorporates the primary control and drive circuit with a discrete avalanche-rated power MOSFET. Crucial system parameters such as maximum ON time and OFF time are fixed during manufacture. Local control circuit decoupling and layout are optimized within the device. Cycle-by-cycle current limiting, soft start, under-voltage lock-out with hysteresis, over-voltage protection, and thermal shutdown protect the device during all normal and overload conditions. Over-voltage protection, thermal shutdown, or an external fault signal are latched. The dual requirements of dielectric isolation and low transient thermal impedance and steady-state thermal resistance are satisfied in an overmolded single-in-line power package. Proven in substantial volumes, this device and its fixed-frequency counterparts represents a significant advance in off-line SMPS reliability growth and integration. A similar off-line switching regulator, with an output rating of 600 V at 6 A, is also available. + FAULT UVLO FDBK FAULT-LATCH TRIGGER & SOFT START REF. Dwg....
