Input supply voltage.
Input supply voltage return. Must always be the lowest potential of all the pins.
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 is divided 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, and is
fed to this pin. An internal blanking circuit eliminates the RC low pass filter that otherwise is required to eliminate leading
edge spike.
A current driven logic input with internal clamp.
A second winding on the Boost inductor senses the flyback voltage associated with the zero crossing of the inductor
current and feeds it to the I
DET
pin through a limiting resistor. Low on this pin causes V
O
(pin 7) to go high.
PWM output pin. A totem-pole output stage specially designed for direct driving the MOSFET.
