TPS628303ADRLR from Texas Instruments, in a SOT-583-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input voltage supply pin accepting 2.25 V to 5.5 V; connect input capacitor between VIN and GND. |
| 2 | GND | power_in | Ground connection pin. |
| 3 | MODE | input | Logic input pin; pull low for PSM/PWM mode, pull high for forced-PWM mode; do not leave floating. |
| 4 | FB | input | Feedback input pin; connect external resistor divider to set output voltage from 0.5 V to 4.5 V. |
| 5 | VOS | input | Output voltage sense input pin; must be connected directly after the inductor. |
| 6 | PG | output | Power good open-drain output pin; sinks up to 1 mA with pullup resistor to voltage ≤ 5.5 V. |
| 7 | SW | power_out | Power stage switching output pin; connects to inductor; switches between near VIN and near GND. |
| 8 | EN | input | Enable/disable logic input pin; pull high to enable device, pull low to disable; do not leave floating. |
