TPS54232DR from Texas Instruments, in a SOIC-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 | BOOT | output | Bootstrap capacitor node for the high-side MOSFET gate driver. Requires a 0.1-µF ceramic capacitor between BOOT and PH; if the BOOT-to-PH voltage falls below the minimum, the high-side MOSFET is forced off until the cap is refreshed. Absolute-max BOOT-to-PH voltage 8 V. |
| 2 | VIN | power_in | Input supply voltage, 3.5 V to 28 V operating (abs-max 30 V). Bypass with a low-ESR ceramic capacitor placed close to the VIN and GND pins. |
| 3 | EN | input | Enable input. Pull below 1.25 V to disable the converter; float (internal pull-up) to enable. Programming the input UVLO threshold and hysteresis with an external two-resistor divider from VIN is recommended. Abs-max 6 V. |
| 4 | SS | input | Slow-start pin. An external capacitor from SS to GND sets the output-voltage rise time and limits inrush current at start-up. |
| 5 | VSENSE | input | Inverting input of the internal gm error amplifier. Connect the top of the output feedback divider here; the internal reference is 0.8 V so VOUT = 0.8 V × (1 + R_top/R_bot). |
| 6 | COMP | output | Transconductance error-amplifier output and input to the PWM comparator. Connect the loop-compensation network (typically series R-C to GND, plus optional high-frequency cap) between COMP and GND. |
| 7 | GND | power_in | Device ground. Return for VIN bypass, compensation, slow-start and feedback-divider components; tie to the board ground plane with a short, low-impedance connection. |
| 8 | PH | output | Switch node - source of the internal high-side power MOSFET. Connects to the external inductor and the cathode of the catch (Schottky) diode. Operating range −0.6 V to 30 V (with a −5 V, 10-ns transient allowance). |
