Connecting a resistor to this pin, sets the minimum oscillator frequency
reached for VFB is below 1.3 V.
A resistor sets the maximum frequency excursion.
A simple resistor adjusts the deadtime length.
Select the soft−start duration.
Applying a voltage above 1.3 V on this pin increases the oscillation frequency
up to Fmax.
Sets the timer duration in presence of a fault.
Detects low input voltage conditions. When brought above Vlatch, it fully
latches off the controller.

−
Drives the low side power MOSFET.
Drives the upper side power MOSFET.
−
Fast shutdown pin, stops all pulses when brought high. Please look in the
description for more details about the fast−fault sequence.
When asserted, the timer starts to countdown and shuts down the controller at
the end of its time duration.
Internal transconductance amplifier.
Non−inverting pin of the OPAMP.
