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 con-
nected 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 3.8V and is connected to this pin.
Input to the PWM comparator. The Current is sensed in the boost
stage by a resistor in the source lead of MOSFET. 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.
The ground potential of all the pins.
The output of a high-current power driver capable of driving
the gate of a power MOSFET.
The logic and control power supply connection.
