LM53601AQDSXTQ1 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. Connect to output inductor. |
| 2 | BOOT | power_in | High side gate driver upper supply rail; connect 100-nF capacitor from SW to BOOT with internal diode charging capacitor while SW is low. |
| 3 | VCC | power_out | Internal 3-V regulator output used as supply to internal control circuits; connect high quality 1.0-μF capacitor from this pin to GND for adjustable versions. |
| 4 | FB | input | Feedback input for adjustable version only; connect to output through voltage divider which determines output voltage set point. |
| 5 | BIAS | power_in | Power source for VCC regulator in adjustable version; connect to output node and place 10-nF bypass capacitor immediately adjacent to this pin. |
| 6 | RESET | output | Open drain reset output; high indicates regulator OK, low indicates regulator fault; connect through current limiting pull up resistor to suitable voltage supply. |
| 7 | EN | input | Enable input to regulator; high enables operation, low disables; can be connected to VIN but do not float. |
| 8 | VIN | power_in | Input supply to regulator with range 3.8V to 36V after startup; connect input bypass capacitors directly between this pin and GND. |
| 9 | SYNC/MODE | input | Multifunction mode control input tolerant to input voltage; external clock synchronization or tied high selects forced PWM mode, tied low selects AUTO mode with diode emulation. |
| 10 | GND | power_in | Ground connection; bypass to VIN immediately adjacent to this pin. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
