PRODUCTION DATA.
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| PGND | 1 | G | Power and analog ground terminal. Connect to bypass capacitor with short, wide traces. Ground reference for internal references and logic. All electrical parameters are measured with respect to this pin. |
| VIN | 2 | P | Input supply to regulator. Connect a high-quality bypass capacitor or capacitors directly to this pin and PGND. |
| EN | 3 | A | Enable input to regulator. High = ON, low = OFF. Can be connected directly to VIN; Do not float. |
| PG | 4 | A | Open-drain power-good flag output. Connect to suitable voltage supply through a current limiting resistor. High = power OK, low = power bad. Flag pulls low when EN = Low. Can be left open when not used. |
| FB | 5 | A | Feedback input to regulator. Connect to tap point of feedback voltage divider. Do not float. Do not ground. |
| VCC | 6 | P | Internal 5-V LDO output. Used as supply to internal control circuits. Do not connect to external loads. Can be used as logic supply for power-good flag. Connect a high-quality 1-µF capacitor from this pin to PGND. |
| BOOT | 7 | P | Bootstrap supply voltage for internal high-side driver. Connect a high-quality 100-nF capacitor from this pin to the SW pin. |
| SW | 8 | P | Regulator switch node. Connect to a power inductor. |
| PAD | THERMAL PAD | Thermal | Major heat dissipation path of the device. A direct thermal connection to a ground plane is required. The PAD is not meant as an electrical interconnect. Electrical characteristics are not ensured. |
| A = Analog, P = Power, G = Ground | |||
