LM25011MY from Texas Instruments, in a MSOP-10-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 | VIN | power_in | Input supply voltage with operating range of 6 V to 42 V and 45 V transient capability. |
| 2 | RT | input | On-time control where external resistor from VIN sets buck switch on-time and switching frequency. |
| 3 | PGD | output | Power Good logic output indicating when feedback voltage exceeds 95% of internal 2.51 V reference with 3.3% hysteresis, requires external pull-up resistor to <7 V. |
| 4 | SS | input | Soft-start input charged by internal 10 µA current source to 2.51 V for controlled startup ramp, supports tracking mode with 0.5 V to 2.6 V input range. |
| 5 | SGND | power_in | Signal ground for all internal circuitry except current limit sense circuit. |
| 6 | FB | input | Feedback input to regulation comparator with 2.51 V internal reference level. |
| 7 | CSG | power_in | Current sense ground connection for current limit detection circuit. |
| 8 | CS | input | Current sense input connected to current sense resistor and free-wheeling diode anode. |
| 9 | SW | output | Switching node output internally connected to buck switch source, connects to external inductor, free-wheeling diode cathode, and bootstrap capacitor. |
| 10 | BST | power_in | Bootstrap capacitor supply for high-side gate driver, charged via internal diode during off-time with 0.1 µF external capacitor. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
