Pin Description
(*) Note that the pin numbering scheme for the Micro SMD package was revised in April, 2002 to conform to JEDEC standard. Only the pin numbers were revised.
No changes to the physical location of the inputs/outputs were made. For reference purpose, the obselete numbering had FB as pin 1, VID1 as pin 2, VID0 as pin
3, SYNC as pin 4, EN as pin 5, PGND as pin 6, SW as pin 7, PVIN as pin 8, VDD as pin 9 and SGND as pin 10.

Switching Node connection to the internal PFET switch and NFET synchronous rectifier.
Power Supply Input to the internal PFET switch. Connect to the input filter capacitor
(Figure 1).
