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
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 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.
