Select the soft- -start duration
A resistor sets the maximum frequency excursion
Sets the timer duration in presence of a fault
Connecting a resistor to this pin, sets the minimum oscillator frequency
reached for VFB = 1 V
Detects low input voltage conditions. When brought above Vlatch, it fully
latches off the controller.
Injecting current in this pin increases the oscillation frequency up to Fmax.
A simple resistor adjusts the dead- -time width
Fast shut- -down pin. Upon release, a clean startup sequence occurs. Can be
used for skip cycle purposes.
When asserted, the timer starts to countdown and shuts down the controller
at the end of its time duration.
