LM2651MTC-3.3 from Texas Instruments, in a TSSOP-16. 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 | Switched-node connection, connected to the source of the internal high-side MOSFET. |
| 2 | SW | output | Switched-node connection, connected to the source of the internal high-side MOSFET. |
| 3 | VIN | power_in | Main power supply pin; recommended VIN supply range is 4 V to 14 V, with an absolute maximum of 15 V. |
| 4 | VIN | power_in | Main power supply pin; recommended VIN supply range is 4 V to 14 V, with an absolute maximum of 15 V. |
| 5 | VIN | power_in | Main power supply pin; recommended VIN supply range is 4 V to 14 V, with an absolute maximum of 15 V. |
| 6 | VCB | input | Bootstrap capacitor connection for high-side gate drive. |
| 7 | AVIN | input | Input supply voltage for control and driver circuits. |
| 8 | SD(SS) | input | Shutdown and soft-start control: pulling this pin below 0.3 V shuts off the regulator, a capacitor to ground sets the input-current control ramp, and it must not be driven by an external source. |
| 9 | FB | input | Output voltage feedback input, connected to the output voltage. |
| 10 | COMP | input | Compensation network connection, connected to the output of the voltage error amplifier. |
| 11 | NC | unconnected | No internal connection. |
| 12 | AGND | power_in | Low-noise analog ground. |
| 13 | AGND | power_in | Low-noise analog ground. |
| 14 | PGND | power_in | Power ground. |
| 15 | PGND | power_in | Power ground. |
| 16 | PGND | power_in | Power ground. |
