GND (Pins 1, 8, 9, 16, 17): The GND pin connections act
as the reference for the regulated output, so load regula-
tion will suffer if the ground end of the load is not at the
same voltage as the GND pins of the IC. This condition will
occur when load current or other currents ?ow through
metal paths between the GND pins and the load ground.
Keep the paths between the GND pins and the load ground
short and use a ground plane when possible. The GND
pin also acts as a heat sink and should be soldered to a
large copper plane to reduce thermal resistance. For the
copper ground plane underneath the device. (See Applica-
tions Information—Layout Considerations.)
SW (Pin 2): The switch pin is the emitter of the on-chip
power NPN switch. This pin is driven up to the input pin
voltage during switch on-time. Inductor current drives the
switch pin negative during switch off-time. Negative volt-
age is clamped with the external catch diode. Maximum
negative switch voltage allowed is – 0.8V.
NC (Pins 3, 5, 7, 13): No Connection.
FE package, the exposed pad should be soldered to the
