LM25010MHX 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 | NC | unconnected | No internal connection; can be connected to ground plane to improve heat dissipation. |
| 2 | SW | output | Switching node internally connected to buck switch source; connect to inductor, free-wheeling diode, and bootstrap capacitor. |
| 3 | BST | input | Bootstrap pin for bootstrap capacitor; capacitor charged from VCC through internal diode during buck switch OFF-time. |
| 4 | ISEN | input | Current sense input; inductor current flows through internal sense resistor during OFF-time with current limit threshold at 1.25 A typical. |
| 5 | SGND | power_in | Current sense ground; recirculating current flows into this pin to the internal current sense resistor. |
| 6 | RTN | power_in | Ground return for all internal circuitry other than the current sense resistor. |
| 7 | NC | unconnected | No internal connection; can be connected to ground plane to improve heat dissipation. |
| 8 | NC | unconnected | No internal connection. |
| 9 | FB | input | Voltage feedback input from regulated output to regulation and overvoltage comparators with 2.5 V regulation threshold. |
| 10 | SS | input | Soft start input; internal 11.5 µA current source charges SS capacitor to 2.5 V for gradual output voltage rise. |
| 11 | RON/SD | input | ON-time control and shutdown; external resistor from VIN sets buck switch ON-time; grounding this pin shuts down regulator. |
| 12 | VCC | power_out | Bias regulator output nominally equal to VIN for VIN < 8.9 V and regulated at 7 V for VIN > 8.9 V; connect 0.47 µF minimum capacitor to ground. |
| 13 | VIN | power_in | Input supply with nominal range 6 V to 42 V; input bypass capacitors located close to VIN and RTN pins. |
| 14 | NC | unconnected | No internal connection. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
