Pin Descriptions  
Pin  
1, 2  
3, 4  
Name  
VIN  
Description  
Application Information  
Input supply voltage Supply pin to the device. Nominal input range is 4.5V to 42V.  
SW  
Switch Node  
Internally connected to the source of the main MOSFET and the drain of the  
synchronous MOSFET. Connect to the output inductor.  
5
BST  
Connection for  
Connect a 33 nF capacitor from the SW pin to this pin. This capacitor is charged through  
bootstrap capacitor an internal diode during the main MOSFET off-time.  
6
7
AGND  
SS  
Analog Ground  
Soft-start  
Ground for all internal circuitry other than the PGND pin.  
A 70 µA internal current source charges an external capacitor of larger than 22 nF to  
provide the soft-start function.  
8
NC  
No Connection  
Ground  
This pin should be left unconnected.  
9, 10  
GND  
Must be connected to the AGND pin for normal operation. The GND and AGND pins  
are not internally connected.  
11  
FB  
Feedback  
Internally connected to the regulation and over-voltage comparators. The regulation  
setting is 0.6V at this pin. Connect to feedback resistors.  
12  
13  
14  
EN  
Enable pin  
Internal pull-up. Connect to a voltage higher than 1.6V to enable the device.  
An external resistor from the VIN pin to this pin sets the main MOSFET on-time.  
RON  
VCC  
On-time Control  
Startup regulator Nominally regulated to 6V. Connect a capacitor of larger than 1 µF between the VCC  
Output  
and AGND pins for stable operation.  
15, 16  
DAP  
PGND  
EP  
Power Ground  
Exposed Pad  
Synchronous MOSFET source connection. Tie to a ground plane.  
Thermal connection pad. Connect to the ground plane.
