Description
This pin is the inverting input of the error amplifier. The output voltage of the boost PFC converter
should be resistively divided to 2.5 V.
This pin is used to detect PFC output over voltage when INV pin information is not correct.
This pin is the output of the transconductance error amplifier. Components for the output voltage
compensation should be connected between this pin and GND.
This pin is the input of the over-current protection comparator. The MOSFET current is sensed
using a sensing resistor and the resulting voltage is applied to this pin. An internal RC filter is
included to filter switching noise.
This pin is the input of the zero-current detection (ZCD) block. If the voltage of this pin goes
higher than 1.5 V, then goes lower than 1.4 V, the MOSFET is turned on.
This pin is used for the ground potential of all the pins. For proper operation, the signal ground
and the power ground should be separated.
This pin is the gate drive output. The peak sourcing and sinking current levels are +500 mA and
-800 mA, respectively. For proper operation, the stray inductance in the gate driving path must be
minimized.
This is the IC supply pin. IC current and MOSFET drive current are supplied using this pin.
