Output of internal regulator. Requires
at least 1-μF external capacitor to
AVSS.

O
Current sense for PWM control and
cycle-by-cycle overcurrent protection.
An input voltage over 1.05 V on
CS_ILIM will trigger an overcurrent in
the PWM controller.

I/O
Fault protection pin. When the
rising threshold of the FAULT pin
is exceeded, the outputs will stop
switching. After the external voltage
drops below the falling threshold, the
device will restart after a set delay.
Connect this pin to AVSS to disable
FAULT.

O
A resistor from RSC to AVSS sets the
desired slope compensation.
I/O
Soft start. An external capacitor
connected to this pin sets the internal
voltage reference rise time. The
voltage on this pin overrides the
internal reference. It can be used for
tracking and sequencing.
