Description
Analog Ground. AGND should be connected directly to DGND.
Input Line Voltage Sense. The VAC signal is referred to PGND.
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.
Overvoltage Protection. The OVP signal is referred to PGND. This signal is used for redundant overvoltage protection.
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.
Fast Current Limiting. This pin is referred to PGND.
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.
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.
Digital Ground. DGND should be connected directly to AGND.
Power Supply Enable Signal. The PSON signal is used to enable/disable the PFC controller. The PSON signal is
referred to DGND.
Output of 2.5 V Regulator. Connect a 100 nF capacitor from VCORE to DGND.
PWM Output for PFC Regulation. The PWM signal is referred to AGND.
Auxiliary PWM Output ( ADP1047 ) or Interleaved PWM Output ( ADP1048 ). The PWM2 signal is referred to AGND.
Open-Drain Output. User-configurable signal from a combination of flags. The AC_OK signal is referred to AGND.
Open-Drain Output. User-configurable signal from a combination of flags. The PGOOD signal is referred to AGND.
Inrush Current Control Signal to an External Inrush Driver. This open-drain output is referred to AGND.
Allows parallel PFC controllers to synchronize to reduce interference. This pin is referred to DGND.
I 2 C Serial Clock Input. The SCL signal is referred to DGND.
I 2 C Serial Data Input and Output (Open-Drain). The SDA signal is referred to DGND.
Thermistor Input. A thermistor is placed from RTD to AGND. The RTD signal is referred to AGND.
Internal Voltage Reference. Connect a 0.1%, 50 kΩ resistor from RES to AGND.
Positive Supply Input. The range is from 3.0 V to 3.6 V. The VDD signal is referred to AGND.
