LM5165XDRCR from Texas Instruments, in a WSON-10-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 | SW | tri_state | Switching node internally connected to the drain of the high-side PMOS buck switch and drain of the low-side NMOS synchronous rectifier; connect to the switching side of the power inductor. |
| 2 | VIN | power_in | Regulator supply input pin to high-side power MOSFET and internal bias rail LDO; path from VIN to input capacitor must be as short as possible. |
| 3 | ILIM | input | Programming pin for current limit that selects one of four preset options when appropriate resistor is connected from ILIM to GND; short ILIM to GND for maximum current setting. |
| 4 | SS | input | Programming pin for soft-start time; if 100-kΩ resistor connected to GND, soft-start is disabled; if open, soft-start ramps in 900 µs; programmable with external capacitance. |
| 5 | RT | input | Mode selection and on-time programming pin for COT control; short to GND to select PFM operation, or connect resistor to GND to program on-time and set switching frequency. |
| 6 | PGOOD | tri_state | Power Good output flag pin connected to drain of internal NFET that holds pin low when FB or VOUT is below regulation target; use 10 kΩ to 100 kΩ pullup resistor to system voltage rail or VOUT (no higher than 12 V). |
| 7 | EN | input | Input pin of precision enable / UVLO comparator; converter is enabled when EN voltage is greater than 1.212 V. |
| 8 | VOUT | input | Feedback input to voltage regulation loop; VOUT pin connects internal feedback resistor divider to regulator output voltage for fixed 3.3-V and 5-V options. |
| 9 | HYS | tri_state | Drain of internal NFET that is turned off when EN input is greater than EN threshold; external resistor from HYS to EN pin UVLO resistor divider programs input UVLO hysteresis voltage. |
| 10 | GND | power_in | Regulator ground return. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
