SS:
When V
this pin is charged, and the output duty is de-
creased by inputting the capacitor voltage to the
PWM.
RT:
The terminal for connecting a resistor to deter-
mine the charge and discharge current of the
triangular wave.
CT:
The terminal for connecting a capacitor to gener-
ate the triangular wave.
CLM( ):
The input terminal for pulse-by-pulse overcurrent
protection. It is usually required to attach an ex-
ternal filter.
