LM2852YMXAX-1.5 from Texas Instruments LM2852YMXAX 1 5 NOPB, in a HTSSOP-14-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | AVIN | power_in | Chip bias / analog input supply. Powers the internal control logic and analog circuitry. Connect to the input voltage (2.85 V to 5.5 V) or a separate rail; filter close to the pin. |
| 2 | EN | input | Enable input. Drive low (to GND) to disable the regulator; drive high (to AVIN) or leave floating to enable it. Pin is internally pulled up. |
| 3 | SGND | power_in | Signal (analog) ground reference for the internal control circuitry. Tie to the PGND / ground plane at a single point near the device. |
| 4 | SS | passive | Soft-start pin. Connect a small capacitor (1 nF to 50 nF) to ground to program the startup ramp. Internal soft-start resistance is ~400 kΩ. |
| 5 | NC | unconnected | No connect. Must be tied to ground or left floating in the application. |
| 6 | PVIN | power_in | Power input to the internal high-side PFET switch (source connection). Bypass with a low-ESR ceramic capacitor (e.g. 22 µF) close to the pin. Must be tied together with pin 7. |
| 7 | PVIN | power_in | Power input to the internal high-side PFET switch (source connection). Must be tied together with pin 6 on the PCB. |
| 8 | SW | power_out | Switch node - drain of the internal high-side PFET and low-side NFET. Connect through the output inductor (e.g. 10 µH) to the load. Must be tied together with pin 9. |
| 9 | SW | power_out | Switch node. Must be tied together with pin 8 on the PCB. |
| 10 | PGND | power_in | Power ground - return for the low-side NFET switch current. Connect to a large ground plane; must be tied together with pin 11. |
| 11 | PGND | power_in | Power ground - return for the low-side NFET switch current. Must be tied together with pin 10. |
| 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 Kelvin-style to VOUT as close to the load as possible; internal sense resistance is ~400 kΩ. This is the regulation feedback point. |
| 15 | EP | power_in | Exposed thermal pad on the underside of the HTSSOP-14 (PowerPAD) package. Must be soldered to a large ground plane / thermal-pad copper for heat dissipation and connected to ground. |
