TPS259570DSGT from Texas Instruments, in a WSON-8-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 | dVdt | passive | Output turn-on slew rate control pin; connect capacitor (up to 3300pF, 4V rated) to GND for desired slew rate, or leave floating for fastest slew rate (absolute maximum 2.5V). |
| 2 | EN/UVLO | input | Active-high enable input with adjustable undervoltage lockout (UVLO) threshold via external resistor divider network (operating range 0 to 6V, do not leave floating). |
| 3 | IN | power_in | Power supply input pin (operating range 2.7V to 18V, absolute maximum -0.3V to 20V). |
| 4 | IN | power_in | Power supply input pin (operating range 2.7V to 18V, absolute maximum -0.3V to 20V). |
| 5 | OUT | power_out | Power output pin; output voltage range 0V to VIN + 0.3V operating, absolute maximum -0.3V to VIN + 0.3V. |
| 6 | FLT | tri_state | Open-drain fault event indicator output pulled low when fault detected; requires external pull-up resistor (operating range 0 to 6V). |
| 7 | ILM | passive | Current limit and load monitoring pin; connect external resistor (487Ω to 5kΩ) to GND to set output current limit (0.5A to 4A range, ±7.5% accuracy), monitor load current via pin voltage (do not leave floating). |
| 8 | GND | power_in | Ground return for power and signal circuits. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
