Pin Configuration  
Figure 2. Pin Diagram, Top View.  
Pin Description  
PIN  
NAME  
FUNCTION  
No Connect. These pins are internally connected to the common drain output of the internal  
MOSFETs. NC(SW) pins are not to be electrically connected to any external signal, ground, or  
voltage. However, they must be soldered to the PCB. Failure to follow this guideline may result  
in part malfunction or damage.  
1, 21-24  
NC(SW)  
Input/Output Power Ground. Connect these pins to the ground electrode of the input and  
output filter capacitors. Refer to Layout Considerations section for details.  
Voltage and Power Output. Connect these pins to output capacitor(s).  
2-3, 8-9  
4-7  
PGND  
VOUT  
Output Voltage Select. These pins set one of seven preset output voltages and the external  
divider option (refer to Electrical Characteristics table for more details), and can be directly  
pulled up to VIN or pulled down to GND; these pins must not be left floating.  
Sense Pin for Internally Programmed Output Voltages with VID Codes. For either VID code or  
10-12  
13  
VS2-0  
VSENSE external resistor divider applications, connect this pin to the last local output filter capacitor for  
internal compensation.  
Feedback Pin for External Voltage Divider Network. Connect a resistor divider to this pin to set  
the output voltage. Use 340 kΩ, 1% or better for the upper resistor.  
Analog Ground for the Controller Circuits  
Analog Voltage Input for the Controller Circuits. Connect this pin to the input power supply.  
Use a 1 μF bypass capacitor on this pin.  
Power OK with an Open Drain Output. Refer to Power OK section.  
Input Enable. A logic high signal on this pin enables the output and initiates a soft start. A  
14  
15  
16  
17  
VFB  
AGND  
AVIN  
POK  
18  
ENABLE logic low signal disables the output and discharges the output to GND. This pin must not be  
left floating.  
19-20  
PVIN  
Input Power Supply. Connect to input supply. Decouple with input capacitor(s) to PGND.
