TPS54226RGTR from Texas Instruments, in a TQFN-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 | VFB | input | Converter feedback input; connect with feedback resistor divider. |
| 2 | VREG5 | power_out | 5.5 V power supply output; a capacitor (typical 1 µF) should be connected to GND. |
| 3 | SS | passive | Soft-start control; an external capacitor should be connected to GND. |
| 4 | GND | power_in | Signal ground pin. |
| 5 | PG | output | Open drain power good output. |
| 6 | EN | input | Enable control input. |
| 7 | PGND1 | power_in | Ground return for low-side MOSFET and input of current comparators; connect PGND and GND strongly together near the IC. |
| 8 | PGND2 | power_in | Ground return for low-side MOSFET and input of current comparators; connect PGND and GND strongly together near the IC. |
| 9 | SW1 | passive | Switch node connection between high-side NFET and low-side NFET; also serves as input to current comparators. |
| 10 | SW2 | passive | Switch node connection between high-side NFET and low-side NFET; also serves as input to current comparators. |
| 11 | SW3 | passive | Switch node connection between high-side NFET and low-side NFET; also serves as input to current comparators. |
| 12 | VBST | passive | Supply input for high-side NFET gate driver (boost terminal); connect capacitor from this pin to the SW terminals, with an internal PN diode between VREG5 and VBST. |
| 13 | VIN1 | power_in | Power input connected to high side NFET drain; VIN range 2 V to 18 V. |
| 14 | VIN2 | power_in | Power input connected to high side NFET drain; VIN range 2 V to 18 V. |
| 15 | VCC | power_in | Supply input for 5 V internal linear regulator for the control circuitry; range 4.5 V to 18 V. |
| 16 | VO | input | Connect to output of converter; used for on-time adjustment. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
