PRODUCTION DATA.
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. |
