LM53600LQDSXRQ1 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 | power_out | Regulator switch node that connects to the output inductor; SW to GND is rated -0.3 V to VIN+0.3 V. |
| 2 | BOOT | input | High-side gate driver upper supply rail; connect a 100-nF capacitor from SW to BOOT, charged by an internal diode while SW is low (BOOT to SW absolute maximum is 3.6 V). |
| 3 | VCC | power_out | Internal 3-V regulator output used as supply for internal control circuits; connect a high-quality 1.0-µF capacitor from this pin to AGND for fixed versions (VCC absolute maximum is 3.6 V). |
| 4 | FB | input | Fixed-version feedback for the output voltage and also the power source for the VCC regulator; connect to the output node with a 10-nF bypass capacitor immediately adjacent to the pin (FB to GND is rated -0.3 V to 16 V for 3.3 V and 5.0 V versions). |
| 5 | AGND | power_in | Fixed-version ground to which the input signals and FB are compared; this pin is the signal ground reference for the regulator control. |
| 6 | RESET | output | Open-drain reset output that requires a current-limiting pull-up resistor to a suitable supply; high means regulator OK, low means regulator fault, and it goes low when EN is low (RESET is rated to 8 V with 8 mA maximum sink current). |
| 7 | EN | input | Enable input: high turns the regulator on, low turns it off; it can be connected to VIN but must not float (EN to GND is rated -0.3 V to 42 V). |
| 8 | VIN | power_in | Input supply to the regulator; connect input bypass capacitors directly between this pin and GND (input voltage range after startup is 3.8 V to 36 V, with VIN absolute maximum of 42 V). |
| 9 | SYNC/MODE | input | Multifunction mode input tolerant of voltages up to VIN: a valid external sync signal forces PWM synchronized to its rising edge, tied high forces PWM at the internal clock, tied low selects AUTO mode with diode emulation at light load; it must not float. |
| 10 | GND | power_in | Power ground for the regulator; bypass to VIN immediately adjacent to this pin. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
