Limiting the duty cycle at high line voltage

protects against magnetic saturation and

minimizes

transients.

Auto-Restart

When VCC is biased from an auxiliary winding

and an open loop condition occurs, the voltage

at the VCC pin increases to 6.5V. When VCC

crosses the threshold voltage, the auto-restart

circuit turns off the power switch and puts the

controller in standby mode. When VCC drops to

4.5V, the startup switch turns on to charge VCC

up again. When VCC crosses 6.0V, the switch

turns off and the standby current discharges

VCC back to 4.5V. After repeating the ramp

cycles between the two threshold voltages 15

times, the auto-restart circuit is disabled and the

controller begins soft-start.
