TPS62090QRGTRQ1 from Texas Instruments, in a VQFN-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 | bidirectional | Switch pin of the power stage; the datasheet lists it as I/O and it is bonded together with pin 2. |
| 2 | SW | bidirectional | Switch pin of the power stage; the datasheet lists it as I/O and it is bonded together with pin 1. |
| 3 | FREQ | input | Selects the switching frequency: Low gives a typical 2.8 MHz and High gives a typical 1.4 MHz; it has an active pulldown of typically 400 kΩ and can be left floating for 2.8 MHz operation. |
| 4 | PG | output | Power-good open-drain output that is high impedance when VOUT is in regulation and pulled low when the output is below nominal; the pullup must not connect to a voltage higher than the device input voltage. |
| 5 | FB | input | Feedback pin; for the adjustable version a resistor divider from the output sets the output voltage. |
| 6 | AGND | power_in | Analog ground; the exposed thermal pad is connected to AGND. |
| 7 | CP | bidirectional | Internal charge-pump flying capacitor terminal; connect a 10-nF capacitor between CP and CN. |
| 8 | CN | bidirectional | 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 for the device; the recommended VIN range is 2.5 V to 6 V. |
| 11 | PVIN | power_in | Power supply input voltage pin; the recommended VIN range is 2.5 V to 6 V and the absolute maximum rating is -0.3 V to 7 V. |
| 12 | PVIN | power_in | Power supply input voltage pin; the recommended VIN range is 2.5 V to 6 V and the absolute maximum rating is -0.3 V to 7 V. |
| 13 | EN | input | Device enable; must be pulled high to enable the device and pulled low to disable it, with an internal pulldown of typically 400 kΩ active when EN is low. |
| 14 | PGND | power_in | Power ground connection. |
| 15 | PGND | power_in | Power ground connection. |
| 16 | VOS | input | Output voltage sense pin that must be connected to the output voltage. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
