The output of the boost converter should be resistively divided to 2.5V and Connected to this pin. 2 COMP Output of the error amplifier. A feedback compensation network is placed between this pin and the INV pin. 3 MULT Input to the multiplier stage. The full wave rectified AC voltage is divided to less than 4V and is connected to this pin. 4 CS Input to the comparator of the control loop. The MOSFET current is sensed by a resister and the resulting voltage is applied to this pin. An internal R/C filter is Included to reject any high frequency noise. 5 IDET Zero current detection input. 6 GND Ground of the control section. 7 OUT Gate drive output. A push pull output stage is able to drive the power MOSFET with peak current of 500mA. 8 Vcc Supply voltage of driver and control circuits.
