TPS62150AQRGTTQ1 from Texas Instruments, in a WQFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Switch node connected to the internal MOSFET switches; connect the inductor between SW and the output capacitor. |
| 2 | SW | output | Switch node connected to the internal MOSFET switches; connect the inductor between SW and the output capacitor. |
| 3 | SW | output | Switch node connected to the internal MOSFET switches; connect the inductor between SW and the output capacitor. |
| 4 | PG | output | Open-drain power good output (High = VOUT ready, Low = VOUT below nominal regulation); requires a pull-up resistor and is rated for a 10 mA sink current. |
| 5 | FB | input | Voltage feedback input of the adjustable version; connect the resistive divider to this pin, and connect it to AGND on fixed-output versions. |
| 6 | AGND | power_in | Analog ground; must be connected directly to the exposed thermal pad and the common ground plane. |
| 7 | FSW | input | Switching frequency select (Low = 2.5 MHz, High = 1.25 MHz for typical operation); has an internal pull-down resistor. |
| 8 | DEF | input | Output voltage scaling (Low = nominal, High = nominal + 5%); has an internal pull-down resistor. |
| 9 | SS/TR | input | Soft-start and tracking pin; an external capacitor sets the internal reference rise time and it can be used for tracking and sequencing. |
| 10 | AVIN | power_in | Supply voltage for the control circuitry (3 V to 17 V recommended operating range); connect to the same source as PVIN. |
| 11 | PVIN | power_in | Supply voltage for the power stage (3 V to 17 V recommended operating range); connect to the same source as AVIN. |
| 12 | PVIN | power_in | Supply voltage for the power stage (3 V to 17 V recommended operating range); connect to the same source as AVIN. |
| 13 | EN | input | Enable input (High = enabled, Low = disabled); has an internal pull-down resistor that keeps the logic level low when floating. |
| 14 | VOS | input | Output voltage sense pin and connection for the control loop circuitry. |
| 15 | PGND | power_in | Power ground; must be connected directly to the exposed thermal pad and the common ground plane. |
| 16 | PGND | power_in | Power ground; must be connected directly to the exposed thermal pad and the common ground plane. |
| 17 | Exposed Thermal Pad | power_in | Must be connected to AGND (pin 6), PGND (pins 15, 16) and the common ground plane, and soldered for appropriate power dissipation and mechanical reliability. |
