When the Error Amplifier output (FB) is low, the
C1 / C2 outputs duty cycle is high.
When the Error Amplifier output (FB) is high, the
C1 / C2 outputs duty cycle is low.
Figure 4 :
When the Soft Start input (SS/DTC) is low, the C1
/ C2 outputs duty cycle is high.
When the Soft Start input (SS/DTC) is high, the C1
/ C2 outputs duty cycle is low.
