3.8
Buck Regulator Shutdown Input
Pin (SHDN1)
SHDN1 is a logic-level input used to turn the buck
regulator on and off. A logic-high (> 45% of VIN), will
enable the regulator output. A logic-low (< 15% of VIN)
will ensure that the output is turned off.
3.9
Buck Regulator Input Voltage Pin
(VIN1)
VIN1 is the buck regulator power input supply pin.
Connect a variable input voltage source to VIN1.
Connect VIN1 and VIN2 together with board traces as
short as possible.
3.10
Buck Inductor Output Pin (LX)
Connect LX directly to the buck inductor. This pin
carries large signal-level current; all connections
should be made as short as possible.
3.11
Power Ground Pin (PGND)
Connect all large-signal level ground returns to PGND.
These large-signal, level ground traces should have a
small loop area and length to prevent coupling of
switching noise to sensitive traces. Please see the
physical layout information supplied in Section 5.0
for
grounding
recommendations.
3.12
Exposed Pad (EP)
For the DFN package, connect the EP to AGND, with
vias into the AGND plane.
