PIN | I/O | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
EN | 1 | I | Enable pin. Pull High to enable the device. Pull Low to disable the device. This pin has an internal pull-down resistor of typically 400kΩ when the device is disabled. |
VIN | 2 | PWR | Input pin. |
GND | 3 | Ground pin. | |
VOUT | 4,5 | PWR | Output pin. |
FB | 6 | I | Feedback reference pin. An external resistor divider connected to this pin programs the output voltage. |
PG | 7 | O | Power good open drain output pin. A pull-up resistor can be connected to any voltage less than 6V. Leave it open if it is not used. |
SS/TR | 8 | I | Soft startup and voltage tracking pin. An external capacitor connected to this pin sets the internal reference voltage rising time. |
Exposed Thermal Pad | The exposed thermal pad must be connected to the GND pin. Must be soldered to achieve appropriate power dissipation and mechanical reliability. |
