TPS62091RGTT from Texas Instruments, in a QFN-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 | power_out | Switch pin of the power stage (datasheet lists its direction as I; typed here as power_out because it is the switching node driving the inductor). |
| 2 | SW | power_out | Switch pin of the power stage (datasheet lists its direction as I; typed here as power_out because it is the switching node driving the inductor). |
| 3 | FREQ | input | Selects switching frequency: FREQ low sets 2.8 MHz typical, FREQ high sets 1.4 MHz typical; it has a ~400 kΩ internal pull-down and can be left floating for 2.8 MHz operation. |
| 4 | PG | output | Open-drain power good output: high impedance when the output is in regulation and pulled low when below nominal; the pull-up resistor must not be connected to any voltage higher than the device input voltage. |
| 5 | FB | input | Feedback pin; for the fixed-output versions (this MPN is the 3.3 V version) connect it to GND for improved thermal performance, or leave it floating since it is internally connected with 400 kΩ to GND. |
| 6 | AGND | power_in | Analog ground; the exposed thermal pad is also connected to AGND. |
| 7 | CP | passive | Internal charge pump flying capacitor terminal; connect a 10 nF capacitor between CP and CN. |
| 8 | CN | passive | Internal charge pump flying capacitor terminal; connect a 10 nF capacitor between CP and CN. |
| 9 | SS | input | Soft-start control pin; a capacitor on this pin sets the soft-start time, and leaving it floating sets the minimum start-up time. |
| 10 | AVIN | power_in | Bias supply input voltage pin (device operates from 2.5 V to 6 V input range). |
| 11 | PVIN | power_in | Power supply input voltage pin (input voltage range 2.5 V to 6 V). |
| 12 | PVIN | power_in | Power supply input voltage pin (input voltage range 2.5 V to 6 V). |
| 13 | EN | input | Device enable: pull high to enable and pull low to disable; it has an internal ~400 kΩ pull-down. |
| 14 | PGND | power_in | Power ground connection. |
| 15 | PGND | power_in | Power ground connection. |
| 16 | VOS | input | Output voltage sense pin; it must be connected to the output voltage. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
