LM536015QDSXRQ1 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 | output | Regulator switch node connecting to output inductor, switching between VIN and GND with maximum voltage VIN+0.3V and minimum -0.3V. |
| 2 | BOOT | input | High side gate driver supply rail; connect 100-nF capacitor from SW pin to BOOT with internal diode charging when SW is low; voltage range -0.3V to 3.6V vs SW. |
| 3 | VCC | power_out | Internal 3V regulator output for control circuits; connect 1.0-μF high-quality capacitor to AGND (fixed version); voltage range -0.3V to 3.6V. |
| 4 | FB | input | Output voltage feedback input for fixed 5V version serving as both feedback and power source for VCC regulator; connect to 5V output node with 10-nF bypass capacitor; voltage range -0.3V to 16V. |
| 5 | AGND | power_in | Ground reference for input signals and FB feedback in fixed versions; voltage offset from GND must not exceed ±1V for durations greater than 1µs. |
| 6 | RESET | output | Open-drain reset output with high indicating regulator OK and low on fault or when EN is low; maximum sink current 8mA; voltage range -0.3V to 8V. |
| 7 | EN | input | Enable input; high enables regulator operation, low disables; can connect to VIN but must not float; tolerant to 42V transient for ≤100ms at ≤1% duty cycle. |
| 8 | VIN | power_in | Input power supply; operating range 3.8V to 36V with 42V maximum transient voltage for ≤100ms at ≤1% duty cycle; connect bypass capacitors directly to GND. |
| 9 | SYNC/MODE | input | Mode control input tolerant to 42V transients; accepts external clock for PWM synchronization at rising edge or internal clock for forced PWM (tied high) or AUTO mode with diode emulation (tied low); must not float. |
| 10 | GND | power_in | Ground return and bypass reference for VIN; bypass capacitors must be connected immediately adjacent to this pin. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
