Pin Function
Pin Name

SHDN/RT
Oscillator Resistor Input. Connecting a resistor to ground from this pin sets
the switching frequency. Forcing this pin to V
DD
causes the device to be shut
down.
External Clock Synchronization Input. The oscillation frequency can be
synchronized to an external oscillation applied to this pin. When tied to V
DD
,
internal oscillator is selected.
Signal Ground. All small-signal components and compensation components
should connect to this ground, which in turn connects to PGND at one point.

PGND
Power Ground. Connect this pin close to the (
) terminal of C
IN
and C
OUT
.

PVDD
Power Input Supply. Decouple this pin to PGND with a capacitor.

6
VDD
Signal Input Supply. Decouple this pin to GND with a capacitor. Normally V
DD
is equal to PVDD.
Power Good Indicator. Open-drain logic output that is pulled to ground when
the output voltage is not within
±
12.5% of regulation point.
Feedback Pin. Receives the feedback voltage from a resistive divider
connected across the output.
Error Amplifier Compensation Point. The current comparator threshold
increases with this control voltage. Connect external compensation elements
to this pin to stabilize the control loop.
