Pin Functions
| PIN (1) | PIN (1) | I/O | DESCRIPTION |
|---|---|---|---|
| NO. | NAME | I/O | DESCRIPTION |
| 1,2,3 | SW | O | Switch node, which is connected to the internal MOSFET switches. Connect inductor between SW and output capacitor. |
| 4 | PG | O | Output power good (High = VOUT ready, Low = VOUT below nominal regulation) ; open drain (requires pull-up resistor) |
| 5 | FB | I | Voltage feedback of adjustable version. Connect 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. | |
| 7 | FSW | I | Switching Frequency Select (Low ≈ 2.5MHz, High ≈ 1.25MHz (2) for typical operation) (3) |
| 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 same source as PVIN. |
| 11,12 | PVIN | I | Supply voltage for power stage. Connect to same source as AVIN. |

- (2) Connect FSW to VOUT or PG in this case.
- (3) An internal pull-down resistor keeps logic level low, if pin is floating.

Typical Application
The TPS6213X is a switched mode step-down converter, able to convert a 3V to 17V input voltage into a 0.9V to 6V output voltage, providing up to 3A. It 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.
