5) Multiplier (COMP and MUL pins)
K=(Multiplier output)/{Vpin3(Vpin2-Vthcomp)}
6) Current detection comparator (IS pin)
7) Brownout (MUL pin)
R1 is resistance between MUL and GND; R2 is resistance between AC voltage line after rectified and MUL pin.
8) Output (OUT pin)
9) Slope compensation (SLOPE pin)
