Signal ground. Keep separate from power grounds (E
1 and E2).
Output of transconductance error amplifier. An R-C compensation network is connected from
this pin to the ground to stabilize the feedback loop. If this pin is pulled lower than 0.15V, the
IC goes into micropower mode.
Error amplifier inverting input. A resistor divider from the output of the converter to this pin sets
its nominal voltage.
LX2172 only. This pin is used to synchronize the device directly with a logic level input pulse.
External synchronization frequency must always be at a higher frequency than the minimum
internal clock. When not used, should be left open.
LX2173 only. This pin is the input to the enable comparator. A voltage under 1.4V will put the
device in micropower mode. Pin must be connected to V
IN when not in use.
Input supply voltage (3.0V to 25V).
Power return of first transistor (Q
1).
This pin must be connected to ground.
Collector of output transistors. Connect to external inductor or input voltage, depending on circuit
topology.
Grounding this pin sets the current limit point to the maximum value. If pin is left open, the current
limit is set to half its maximum value.
