MP1593DN-LF-Z from Monolithic Power Systems, in a SOIC-8-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 | BS | input | High-side gate drive boost input supplying the drive for the high-side N-channel MOSFET; connect a 10nF or greater capacitor from SW to BS. |
| 2 | IN | power_in | Power input supplying the IC, to be driven from a 4.75V to 28V source and bypassed to GND with a suitably large capacitor. |
| 3 | SW | power_out | Power switching output node that supplies power to the output LC filter; a capacitor is required from SW to BS. |
| 4 | GND | power_in | Ground; the exposed pad on the package must be connected to pin 4. |
| 5 | FB | input | Feedback input that senses the output voltage through a resistive divider, with the feedback threshold stated as 1.222V. |
| 6 | COMP | passive | Compensation node for the regulation loop, with a series RC network connected from COMP to GND and an additional capacitor sometimes required. |
| 7 | EN | input | Enable input that turns the regulator on when driven high and off when low; it must be below 1.5V for complete low-current shutdown and can be left disconnected for automatic startup. |
| 8 | SS | input | Soft-start control input where a capacitor from SS to GND sets the soft-start period (0.1μF gives 10ms), and leaving it disconnected disables soft-start. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
