AGND should be connected directly to DGND. 2 VAC Input Line Voltage Sense. The VAC signal is referred to PGND. 3 VFB Feedback Voltage Sense. The VFB signal is referred to PGND. VFB is the feedback signal for PFC power circuit regulation. It is used as the analog voltage input to the VFB ADC. 4 OVP Overvoltage Protection. The OVP signal is referred to PGND. This signal is used for redundant overvoltage protection. 5 PGND Power Ground. PGND is the connection for the ground line of the power rail. There should be a low impedance path between PGND and AGND. 6 ILIM Fast Current Limiting. This pin is referred to PGND. 7 NC/IBAL ADP1047: No Connect. Do not connect to this pin. ADP1048: Current Balancing Input for Interleaved Operation. The IBAL input is referred to PGND. 8 CS− Differential Current Sense Negative Input. The CS− signal is used for current measurement, monitoring, and protection. A 0.1%, 10 kΩ resistor must be used to connect to this circuit. 9 CS+ Differential Current Sense Positive Input. The CS+ signal is used for current measurement, monitoring, and protection. A 0.1%, 10 kΩ resistor must be used to connect to this circuit. 10 DGND Digital Ground. DGND should be connected directly to AGND. 11 PSON Power Supply Enable Signal. The PSON signal is used to enable/disable the PFC controller. The PSON signal is referred to DGND. 12 VCORE Output of 2.5 V Regulator. Connect a 100 nF capacitor from VCORE to DGND. 13 PWM PWM Output for PFC Regulation. The PWM signal is referred to AGND. 14 PWM2 Auxiliary PWM Output (ADP1047) or Interleaved PWM Output (ADP1048). The PWM2 signal is referred to AGND. 15 AC_OK Open-Drain Output. User-configurable signal from a combination of flags. The AC_OK signal is referred to AGND. 16 PGOOD Open-Drain Output. User-configurable signal from a combination of flags. The PGOOD signal is referred to AGND. 17 INRUSH Inrush Current Control Signal to an External Inrush Driver. This open-drain output is referred to AGND. 18 SYNC Allows parallel PFC controllers to synchronize to reduce interference. This pin is referred to DGND. 19 SCL I2C Serial Clock Input. The SCL signal is referred to DGND. 20 SDA I2C Serial Data Input and Output (Open-Drain). The SDA signal is referred to DGND. 21 ADD Address Select Input.
