Pin Functions

PIN I/O DESCRIPTION
NAME NO.
SW 1 — Switch pin of the converter. The inductor is connected here.
PGND 2 — Power ground for the converter
AGND 3 — Analog ground connection
FB 4 I Feedback voltage sense input. Connect directly to VOUT or to the midpoint of an external voltage divider for the adjustable version.
OVT 5 I Output voltage tracking input. The signal applied to this pin is used as reference voltage overriding the internal reference voltage when it is below the internal 0.6-V reference. If this feature is not used, the OVT pin is connected to VIN.
EN 6 I Enable pin. A logic high enables the regulator, a logic low disables the regulator. This pin needs to be terminated and not left floating.
MODE 7 I This pin is used to force fixed frequency PWM operation or to synchronize the device to an external clock signal. With MODE = High, the device is forced into 1.5-MHz fixed frequency PWM operation. With MODE = Low, the device automatically enters the power save mode at light load currents.
PG 8 O Power good indication. This is a open drain output that is low when the device is disabled or the output voltage drops 10% below target.
AVIN 9 — Power supply for control circuitry. Must be connected to the same voltage supply as PVIN through RC filter.
PVIN 10 — Input voltage for the power stage. VIN must be connected to the same voltage supply as AVIN.
Exposed Thermal Pad C2 — Connect the exposed thermal pad to analog ground AGND.
