After a CH6 soft start, when the CTL1, 2, CTL3, CTL4, and CTL5 terminals are driven high
The capacitor (Cs) connected to the CS terminal (pin 15) starts charging and the error amp provides a soft start
by comparing the CH1 to CH5 output voltage to the voltage at the CS terminal.
Note : Each of the terminals CTL1,2, CTL3, CTL4, and CTL5 can be switched on or off independently. When any of
these CTL terminals is switched on, a soft start operation is provided as shown in the above timing chart.
