Symbol
Description
1
NC
Not connected.
2
PS
Power and voltage sense input. This dual function input provides both feedback voltage sensing
and internal chip power. It should be connected to the regulator output. (See Section 4.0,
Applications).
3
SHDN
Shutdown input. A logic low on this input suspends device operation and supply current is
reducedtolessthan0.5
A. The device resumes normal operation when SHDN is again brought
high.
4
LX
Inductor switch output. LX is the drain of an internal N-channel switching transistor. This terminal
drives the external inductor, which ultimately provides current to the load.
5
GND
Ground terminal.
