NC — No connections
IAC
3IN
Rectifier Voltage Sense — A current proportional to the rectified line voltage (Vrect) is
fed into this pin. The current is measured with an A/D converter.
IFB
4IN
Link Voltage Sense — A current proportional to the output link voltage (Vlink) of the
PFC is fed into this pin. The current is measured with an A/D converter.
GND
5PWR
Ground — Current return for both the input signal portion of the IC and the gate driver.
GD
6OUT
Gate Driver Output — The totem pole stage is able to drive the power MOSFET with a
peak current of 0.5 A source and 1.0 A sink. The high-level voltage of this pin is
clamped at VZ to avoid excessive gate voltages.
VDD
7PWR
IC Supply Voltage — Supply voltage of both the input signal portion of the IC and the
gate driver.
