| 4 | PG | O | Output power good (High = V OUT ready, Low = V OUT below nominal regulation); open drain (requires pullup resistor) |
| 5 | FB | I | Voltage feedback of adjustable version. Connect a resistive voltage divider to this pin. It is recommended to connect FB to AGND on fixed output voltage versions for improved thermal performance. |
| 6 | AGND | Analog Ground. Must be connected directly to the Exposed Thermal Pad and common ground plane. | |

| 8 | DEF | I | Output voltage scaling (Low = nominal, High = nominal + 5%) (3) |
| 9 | SS/TR | I | Soft-Start/Tracking Pin. An external capacitor connected to this pin sets the internal voltage reference rise time. It can be used for tracking and sequencing. |
| 10 | AVIN | I | Supply voltage for control circuitry. Connect to the same source as PVIN. |
| 11,12 | PVIN | I | Supply voltage for power stage. Connect to the same source as AVIN. |
| 13 | EN | I | Enable input (High = enabled, Low = disabled) (3) |
| 14 | VOS | I | Output voltage sense pin and connection for the control loop circuitry |
| 15,16 | PGND | Power Ground. Must be connected directly to the Exposed Thermal Pad and common ground plane. | |
| Exposed Thermal Pad | Must be connected to AGND (pin 6), PGND (pin 15,16), and common ground plane. See the Layout Example . Must be soldered to achieve appropriate power dissipation and mechanical reliability. |

Typical Application
The TPS6213x is a switched mode step-down converter that is able to convert a 3V- to 17-V input voltage into a 0.9-V to 6-V output voltage, providing up to 3 A. The device needs a minimum amount of external components. Apart from the LC output filter and the input capacitors, only the TPS62130 (TPS62130A) with adjustable output voltage needs an additional resistive divider to set the output voltage level.
