HIDRV  
High Side FET Driver. Connect this pin to the gate of an N-channel MOSFET. The  
trace from this pin to the MOSFET gate should be <0.5".  
SW  
High Side Driver Source and Low Side Driver Drain Switching Node. Together  
with DROOP and ILIM pins allows FET sensing for VCC current.  
GNDA  
Analog Ground. Return path for low power analog circuitry. This pin should be  
connected to a low impedance system ground plane to minimize ground loops.  
VID4/  
VID25mV  
Multi-Value Voltage Identification Code Input. This open collector/TTL  
compatible input will program the output voltage over the ranges specified in Table  
1 (for the FAN5056V90) or Table 2 (for the FAN5056V85). A pull-up resistor is  
internal to the controller.  
5-8  
VID3-0  
Voltage Identification Code Inputs. These open collector/TTL compatible inputs  
will program the output voltage over the ranges specified in Table 1 (for the  
FAN5056V90) or Table 2 (for the FAN5056V85). Pull-up resistors are internal to the  
controller.

VTTFB  
Gate Driver for VTT Transistor. For 1.5V output.

16  
Voltage Feedback for VTT.  
VCKGATE Gate Driver for VCK Transistor. For 2.5V output.  
VCKFB  
Voltage Feedback for VCK.  
Voltage Feedback for VAGP.  
VAGPFB  
VAGPGATE Gate Driver for VAGP Transistor. For 3.3/1.5V output.  
TYPEDET Type Detect. Sets 3.3V or 1.5V for AGP.  
ENABLE/SS Output Enable. A logic LOW on this pin will disable all outputs. An internal current  
source allows for open collector control. This pin also doubles as soft start for all  
outputs.  
17  
18  
PWRGD  
Power Good Flag. An open collector output that will be logic LOW if any output  
voltage is not within ±14% of the nominal output voltage setpoint.  
ILIM  
VCC Current Feedback. Pin 18 is used in conjunction with pin 2 as the input for the  
VCC current feedback control loop. Layout of these traces is critical to system  
performance. See Application Information for details.  
19  
20  
DROOP  
VFB  
Droop Set. Use this pin to set magnitude of active droop.  
Vcc Voltage Feedback. Pin 20 is used as the input for the VCC voltage feedback  
control loop. See Application Information for details regarding correct layout.  
21  
VCCA  
Analog VCC. Connect to system 5V supply and decouple with a 0.1µF ceramic  
capacitor.
