The STR-S6707, STR-S6708, and STR-S6709 are specifically
designed to meet the requirement for increased integration and reliabil-
ity in off-line quasi-resonant flyback converters. These devices incorpo-
rate the primary control and proportional drive circuit with a third-
generation high-voltage bipolar switching transistor.
Crucial system parameters such as maximum ON time and OFF
time are fixed during manufacture. Local control circuit decoupling and
layout are optimized within each device.
Cycle-by-cycle current limiting, under-voltage lock-out with hyster-
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.
Proven in substantial volumes, these devices and their fixed-
frequency counterparts represent a significant advance in off-line SMPS
reliability growth and integration.
