STR-S6513
OFF-LINE SWITCHING REGULATOR
– WITH POWER MOSFET OUTPUT
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 ava-
lanche-rated power MOSFET.

Crucial system parameters such as maximum ON time and OFF
time are fixed during manufacture. Local control circuit decoupling and

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 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 600 V at 6 A, is also available.

APPLICATIONS INFORMATION
WARNING — These devices are designed to be operated at lethal voltages and energy levels.
Circuit designs that embody these components must conform with applicable safety requirements.
Precautions must be taken to prevent accidental contact with power-line potentials.
Do not connect grounded test equipment.
The use of an isolation transformer is recommended during circuit development and breadboarding.
The power MOSFET outputs of these devices are similar to the International Rectifier type IRF740. These devices
feature an excellent combination of fast switching, ruggedized device design, low on-resistance, and cost effectiveness.
Recommended mounting hardware torque:
4.34 – 5.79 lbf•ft (6 – 8 kg•cm or 0.588 – 0.784 Nm).
Recommended metal-oxide-filled, alkyl-degenerated oil base, silicone grease:
Dow Corning 340, or equivalent
