Pin Name
Pin Function Descrition
1
INV
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 conpensation network is
placed between this pin and the INV pin.
Input to the multiplier stage. The full-wave rectified AC is devided to
less than 2V and is connected to this pin.
Input to the PWM comparator. Current is sensed in the boost stage
MOSFET by a resistor in the source lead. An internal leading edge
blanking circuitry has been included to reject any high frequency noise
present on the current waveform.
The zero current detector senses the inductor current by monitoring
when the boost inductor auxilary winding voltage falls below 1.8V. If it
is connected to GND, the device is disabled.
The ground potential of all the pins.
Gate driver output . A push pull output stage is able to drive the Power
MOSFET with peak current of 400mA.
Supply voltage of driver and control circuits.
