LM2852YMXAX-3.3 from Texas Instruments, in a HTSSOP-14-EP. 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 | AVIN | power_in | Chip bias input that supplies power to the chip's logic; connect to the input voltage or a separate rail. |
| 2 | EN | input | Enable input: connect to ground to disable the chip, or connect to AVIN or leave floating to enable it, since it is internally pulled up. |
| 3 | SGND | power_in | Signal ground for the control circuitry; all ground connections must be tied together per the layout guidelines. |
| 4 | SS | passive | Soft-start pin that connects to a small capacitor to control startup; the soft-start capacitance is restricted to 1 nF to 50 nF. |
| 5 | NC | unconnected | No connect; must be tied to ground or left floating in the application. |
| 6 | PVIN | power_in | Input supply pin connected to the input voltage and to the source of the internal power PFET. |
| 7 | PVIN | power_in | Input supply pin connected to the input voltage and to the source of the internal power PFET. |
| 8 | SW | output | Switch pin; connect to the output inductor. |
| 9 | SW | output | Switch pin; connect to the output inductor. |
| 10 | PGND | power_in | Power ground; connect to an internal ground plane or other large ground plane. |
| 11 | PGND | power_in | Power ground; connect to an internal ground plane or other large ground plane. |
| 12 | NC | unconnected | No connect; must be tied to ground or left floating in the application. |
| 13 | NC | unconnected | No connect; must be tied to ground or left floating in the application. |
| 14 | SNS | input | Output voltage sense pin; connect to the output voltage as close to the load as possible. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
