LM5010MHX 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. |
| 2 | SW | output | Switching node internally connected to buck switch source; connect to inductor, free-wheeling diode, and bootstrap capacitor. |
| 3 | BST | input | Boost pin for bootstrap capacitor; connect 0.022-µF capacitor from SW to this pin, charged from VCC through internal diode during OFF-time. |
| 4 | ISEN | input | Current sense input; recirculating current flows through internal sense resistor and out this pin to free-wheeling diode; current limit nominally 1.25 A. |
| 5 | SGND | power_in | Sense ground; recirculating current flows into this pin to current sense resistor. |
| 6 | RTN | power_in | Circuit ground for all internal circuitry other than current limit detection. |
| 7 | NC | unconnected | No connection. |
| 8 | NC | unconnected | No connection. |
| 9 | FB | input | Feedback input from regulated output; internally connected to regulation and overvoltage comparators; regulation level 2.5 V. |
| 10 | SS | input | Soft start input; internal 11.5-µA current source charges external capacitor to 2.5 V for soft start function. |
| 11 | RON/SD | input | ON-time control and shutdown input; external resistor from VIN to this pin sets buck switch ON-time; grounding this pin shuts down regulator. |
| 12 | VCC | power_in | Output from startup regulator nominally 7 V; external voltage 7.5 V to 14 V can be applied to reduce internal dissipation; internal diode to VIN. |
| 13 | VIN | power_in | Input supply with nominal range 8 V to 75 V. |
| 14 | NC | unconnected | No connection. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
