TPS72018DRVR from Texas Instruments, in a WSON-6-EP(2x2). 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 | OUT | output | Output pin. A 2.2-μF ceramic capacitor is connected from this pin to ground, for stability and to provide load transients. |
| 2 | NC | unconnected | No connection. |
| 3 | EN | input | Enable pin. A logic high signal on this pin turns the device on and regulates the voltage from IN to OUT. A logic low on this pin turns off the device. |
| 4 | BIAS | input | Bias supply pin. TI recommends bypassing this input with a ceramic capacitor to ground for better transient performance. |
| 5 | GND | power_in | Ground pin. |
| 6 | IN | input | Input pin. This pin can be a maximum of 4.5 V; VIN must not exceed VBIAS. Bypass this input with a ceramic capacitor to ground. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
