Sets the channel 3 soft start time.
Set the time by connecting a capacitor between
this pin and ground. Note that although the
channel 3 maximum on duty is set internally to
86%, the maximum on duty can be set to a value
of 86% or less by inserting a resistor between
this pin and ground, and can be set to a value of
86% or more by inserting a resistor between this
