Pin Function Description
Inverting input of the error amplifier. the output of the boost converter
should be resistively divided to 2.5V and connected to this pin.
The output of the error amplifier. a feedback compensation network is
placed between this pin and the INV pin.
Input to the multiplier stage. the full-wave rectified ac voltage is
divided to less than 2V and is connected to this pin.
Input of the PWM comparator. the MOSFET current is sensed by a
resistor and the resulting voltage is applied to this pin. an internal R/C
filter is included to reject any high frequency noise.
Zero current detection input.
The ground potential of all the pins.
Gate driver output. the push pull output stage is able to drive the
power MOSFET with peak current of 500mA.
Supply voltage of driver and control circuits.
