Overview
STR-M6511 OFF-LINE SWITCHING REGULATOR – WITH POWER MOSFET OUTPUT DRAIN 1 OSC.
FAULT LATCH Data Sheet 28102 SOURCE 2 R COMMON OVER-CURRENT PROTECTION V IN S The STR-M6511 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 devices 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 over-molded 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 800 V at 10 A, is also available.
