SHDN
Shutdown input. A logic low on this input suspends device operation and
supply current is reduced to less than 0.5
μ
A. The device resumes normal
operation when SHDN is again brought high.
Voltage sense input. This input provides feedback voltage sensing to the
internal error amplifier. It must be connected to the output voltage node,
preferably the single point in the system where tight voltage regulation is
most beneficial.
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 Figure 3-1).
Power supply voltage input.
Not connected.
Ground terminal.
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.
