time are fixed during manufacture. Local control circuit decoupling and

layout are optimized within each device.

esis, over-voltage protection, and thermal shutdown protect these

devices during all normal and overload conditions. Over-voltage

protection and thermal shutdown are latched after a short delay. A

versatile triple-level inhibit circuit includes the OFF time synchronization

required to establish quasi-resonant operation. The inhibit function has

also been expanded to initiate operation in stand-by mode in which the

power supply delivers a small fraction of the steady-state output power.

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.

frequency counterparts represent a significant advance in off-line SMPS

reliability growth and integration.
