LM5010AMHX from Texas Instruments, 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 | NC | unconnected | No connection; can be connected to ground plane to improve heat dissipation. |
| 2 | SW | output | Switching node output internally connected to the buck switch source; connects to inductor, freewheeling diode, and bootstrap capacitor. |
| 3 | BST | input | Bootstrap capacitor pin charged from VCC through an internal diode during the buck switch OFF-time. |
| 4 | ISEN | input | Current sense input where inductor current flows through internal 50 mΩ sense resistor with 1.25 A typical threshold for current limiting. |
| 5 | SGND | power_in | Sense ground where recirculating inductor current flows into this pin through the internal sense resistor. |
| 6 | RTN | power_in | Circuit ground return for all internal circuitry other than the current sense resistor. |
| 7 | NC | unconnected | No connection; can be connected to ground plane to improve heat dissipation. |
| 8 | NC | unconnected | No connection; can be connected to ground plane to improve heat dissipation. |
| 9 | FB | input | Voltage feedback input to regulation and overvoltage comparators with 2.5 V regulation level and 2.9 V overvoltage threshold. |
| 10 | SS | input | Soft-start pin charged by an internal 11.5 µA current source to 2.5 V for gradual output voltage ramp during startup. |
| 11 | RON/SD | input | ON-time control and shutdown pin where external resistor from VIN to this pin sets buck switch ON-time; grounding 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; requires 0.47 µF minimum bypass capacitor. |
| 13 | VIN | power_in | Input supply pin with nominal range 6 V to 75 V; input bypass capacitors must be located as close as possible to VIN and RTN pins. |
| 14 | NC | unconnected | No connection; can be connected to ground plane to improve heat dissipation. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
