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.

time are fixed during manufacture. Local control circuit decoupling and

layout are optimized within the device.

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.

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.
