OFF-LINE QUASI-RESONANT FLYBACK SWITCHING
REGULATOR
The STR-G6653 is specifically designed to satisfy the requirements for increased integration and reliability in off-line quasi-resonant flyback converters.
This device incorporates the primary control and drive circuit with a discrete avalanche-rated power MOSFET.
Cycle-by-cycle current limiting, under-voltage lockout with hysteresis, over-voltage protection, and thermal shutdown protects the power supply during the normal overload and fault conditions.
Over-voltage protection and thermal shutdown are latched after a short delay.
The latch may be...
